DETAILED DESCRIPTION

Guidelines for Interpreting the Present Application

The following sections I-X provide a guide to interpreting the present application.

I. Terms

The term “product” means any machine, manufacture and/or composition of matter, unless expressly specified otherwise.

The term “process” means any process, algorithm, method or the like, unless expressly specified otherwise.

Each process (whether called a method, algorithm or otherwise) inherently includes one or more steps, and therefore all references to a “step” or “steps” of a process have an inherent antecedent basis in the mere recitation of the term ‘process’ or a like term. Accordingly, any reference in a claim to a ‘step’ or ‘steps’ of a process has sufficient antecedent basis.

The term “invention” and the like mean “the one or more inventions disclosed in this application”, unless expressly specified otherwise.

The terms “an embodiment”, “embodiment”, “embodiments”, “the embodiment”, “the embodiments”, “one or more embodiments”, “some embodiments”, “certain embodiments”, “one embodiment”, “another embodiment” and the like mean “one or more (but not all) embodiments of the disclosed invention(s)”, unless expressly specified otherwise.

The term “variation” of an invention means an embodiment of the invention, unless expressly specified otherwise.

A reference to “another embodiment” in describing an embodiment does not imply that the referenced embodiment is mutually exclusive with another embodiment (e.g., an embodiment described before the referenced embodiment), unless expressly specified otherwise.

The terms “including”, “comprising” and variations thereof mean “including but not limited to”, unless expressly specified otherwise.

The terms “a”, “an” and “the” mean “one or more”, unless expressly specified otherwise.

The term “plurality” means “two or more”, unless expressly specified otherwise.

The term “herein” means “in the present application, including anything which may be incorporated by reference”, unless expressly specified otherwise.

The phrase “at least one of”, when such phrase modifies a plurality of things (such as an enumerated list of things) means any combination of one or more of those things, unless expressly specified otherwise. For example, the phrase “at least one of a widget, a car and a wheel” means either (i) a widget, (ii) a car, (iii) a wheel, (iv) a widget and a car, (v) a widget and a wheel, (vi) a car and a wheel, or (vii) a widget, a car and a wheel. The phrase “at least one of”, when such phrase modifies a plurality of things does not mean “one of each of” the plurality of things.

Numerical terms such as “one”, “two”, etc. when used as cardinal numbers to indicate quantity of something (e.g., one widget, two widgets), mean the quantity indicated by that numerical term, but do not mean at least the quantity indicated by that numerical term. For example, the phrase “one widget” does not mean “at least one widget”, and therefore the phrase “one widget” does not cover, e.g., two widgets.

The phrase “based on” does not mean “based only on”, unless expressly specified otherwise. In other words, the phrase “based on” describes both “based only on” and “based at least on”. The phrase “based at least on” is equivalent to the phrase “based at least in part on”.

The term “represent” and like terms are not exclusive, unless expressly specified otherwise. For example, the term “represents” do not mean “represents only”, unless expressly specified otherwise. In other words, the phrase “the data represents a credit card number” describes both “the data represents only a credit card number” and “the data represents a credit card number and the data also represents something else”.

The term “whereby” is used herein only to precede a clause or other set of words that express only the intended result, objective or consequence of something that is previously and explicitly recited. Thus, when the term “whereby” is used in a claim, the clause or other words that the term “whereby” modifies do not establish specific further limitations of the claim or otherwise restricts the meaning or scope of the claim.

The term “e.g.” and like terms mean “for example”, and thus does not limit the term or phrase it explains. For example, in the sentence “the computer sends data (e.g., instructions, a data structure) over the Internet”, the term “e.g.” explains that “instructions” are an example of “data” that the computer may send over the Internet, and also explains that “a data structure” is an example of “data” that the computer may send over the Internet. However, both “instructions” and “a data structure” are merely examples of “data”, and other things besides “instructions” and “a data structure” can be “data”.

The term “respective” and like terms mean “taken individually”. Thus if two or more things have “respective” characteristics, then each such thing has its own characteristic, and these characteristics can be different from each other but need not be. For example, the phrase “each of two machines has a respective function” means that the first such machine has a function and the second such machine has a function as well. The function of the first machine may or may not be the same as the function of the second machine.

The term “i.e.” and like terms mean “that is”, and thus limits the term or phrase it explains. For example, in the sentence “the computer sends data (i.e., instructions) over the Internet”, the term “i.e.” explains that “instructions” are the “data” that the computer sends over the Internet.

Any given numerical range shall include whole and fractions of numbers within the range. For example, the range “1 to 10” shall be interpreted to specifically include whole numbers between 1 and 10 (e.g., 1, 2, 3, 4, . . . 9) and non-whole numbers (e.g., 1.1, 1.2, . . . 1.9).

Where two or more terms or phrases are synonymous (e.g., because of an explicit statement that the terms or phrases are synonymous), instances of one such term/phrase does not mean instances of another such term/phrase must have a different meaning. For example, where a statement renders the meaning of “including” to be synonymous with “including but not limited to”, the mere usage of the phrase “including but not limited to” does not mean that the term “including” means something other than “including but not limited to”.

As used herein, the term “conducting” may be used in the context of a game, such as in the phrase “conducting a game”. Conducting a game may include receiving a bet, storing a record of the amount of the bet, determining or generating an outcome of a game (e.g., such as by the execution of an algorithm for generating random outcome), determining an amount to be paid out as a payout based on the outcome and the bet (e.g., determining a multiple of the bet to be paid out in the event of a winning outcome), paying or directing that the payout be paid, and performing any other aspect of a game. In various embodiments, a game may be conducted by a remote entity. For example, though a player may interact with a mobile gaming device, the casino server may generate the outcomes that occur in games of the player. In various embodiments, a game may be conducted by a proximate entity, such as a mobile gaming device with which a player interacts. In various embodiments, a game may be conducted jointly by a proximate and remote entity. For example, a mobile gaming device and the casino server may jointly conduct a game.

As used herein, the term “stationary device” may include a stationary game gaming device, a terminal used for gaming, and a table game as well as any device not used for gaming. For example, a stationary device may include a slot machine, a video poker machine, a terminal at which players may place bets, a blackjack table, and a poker table, as well as a display screen, a kiosk, an ATM, etc.

II. Determining

The term “determining” and grammatical variants thereof (e.g., to determine a price, determining a value, determine an object which meets a certain criterion) is used in an extremely broad sense. The term “determining” encompasses a wide variety of actions and therefore “determining” can include calculating, computing, processing, deriving, investigating, looking up (e.g., looking up in a table, a database or another data structure), ascertaining and the like. Also, “determining” can include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory) and the like. Also, “determining” can include resolving, selecting, choosing, establishing, and the like.

The term “determining” does not imply certainty or absolute precision, and therefore “determining” can include estimating, extrapolating, predicting, guessing and the like.

The term “determining” does not imply that mathematical processing must be performed, and does not imply that numerical methods must be used, and does not imply that an algorithm or process is used.

The term “determining” does not imply that any particular device must be used. For example, a computer need not necessarily perform the determining.

III. Forms of Sentences

Where a limitation of a first claim would cover one of a feature as well as more than one of a feature (e.g., a limitation such as “at least one widget” covers one widget as well as more than one widget), and where in a second claim that depends on the first claim, the second claim uses a definite article “the” to refer to the limitation (e.g., “the widget”), this does not imply that the first claim covers only one of the feature, and this does not imply that the second claim covers only one of the feature (e.g., “the widget” can cover both one widget and more than one widget).

When an ordinal number (such as “first”, “second”, “third” and so on) is used as an adjective before a term, that ordinal number is used (unless expressly specified otherwise) merely to indicate a particular feature, such as to distinguish that particular feature from another feature that is described by the same term or by a similar term. For example, a “first widget” may be so named merely to distinguish it from, e.g., a “second widget”. Thus, the mere usage of the ordinal numbers “first” and “second” before the term “widget” does not indicate any other relationship between the two widgets, and likewise does not indicate any other characteristics of either or both widgets. For example, the mere usage of the ordinal numbers “first” and “second” before the term “widget” (1) does not indicate that either widget comes before or after any other in order or location; (2) does not indicate that either widget occurs or acts before or after any other in time; and (3) does not indicate that either widget ranks above or below any other, as in importance or quality. In addition, the mere usage of ordinal numbers does not define a numerical limit to the features identified with the ordinal numbers. For example, the mere usage of the ordinal numbers “first” and “second” before the term “widget” does not indicate that there must be no more than two widgets.

When a single device, article or other product is described herein, more than one device/article (whether or not they cooperate) may alternatively be used in place of the single device/article that is described. Accordingly, the functionality that is described as being possessed by a device may alternatively be possessed by more than one device/article (whether or not they cooperate).

Similarly, where more than one device, article or other product is described herein (whether or not they cooperate), a single device/article may alternatively be used in place of the more than one device or article that is described. For example, a plurality of computer-based devices may be substituted with a single computer-based device. Accordingly, the various functionality that is described as being possessed by more than one device or article may alternatively be possessed by a single device/article.

The functionality and/or the features of a single device that is described may be alternatively embodied by one or more other devices which are described but are not explicitly described as having such functionality/features. Thus, other embodiments need not include the described device itself, but rather can include the one or more other devices which would, in those other embodiments, have such functionality/features.

IV. Disclosed Examples and Terminology are not Limiting

Neither the Title (set forth at the beginning of the first page of the present application) nor the Abstract (set forth at the end of the present application) is to be taken as limiting in any way as the scope of the disclosed invention(s). An Abstract has been included in this application merely because an Abstract of not more than 150 words is required under 37 C.F.R. § 1.72(b).

The title of the present application and headings of sections provided in the present application are for convenience only, and are not to be taken as limiting the disclosure in any way.

Numerous embodiments are described in the present application, and are presented for illustrative purposes only. The described embodiments are not, and are not intended to be, limiting in any sense. The presently disclosed invention(s) are widely applicable to numerous embodiments, as is readily apparent from the disclosure. One of ordinary skill in the art will recognize that the disclosed invention(s) may be practiced with various modifications and alterations, such as structural, logical, software, and electrical modifications. Although particular features of the disclosed invention(s) may be described with reference to one or more particular embodiments and/or drawings, it should be understood that such features are not limited to usage in the one or more particular embodiments or drawings with reference to which they are described, unless expressly specified otherwise.

No embodiment of method steps or product elements described in the present application constitutes the invention claimed herein, or is essential to the invention claimed herein, or is coextensive with the invention claimed herein, except where it is either expressly stated to be so in this specification or expressly recited in a claim.

All words in every claim have the broadest scope of meaning they would have been given by a person of ordinary skill in the art as of the priority date. No term used in any claim is specially defined or limited by this application except where expressly so stated either in this specification or in a claim.

The preambles of the claims that follow recite purposes, benefits and possible uses of the claimed invention only and do not limit the claimed invention.

The present disclosure is not a literal description of all embodiments of the invention(s). Also, the present disclosure is not a listing of features of the invention(s) which must be present in all embodiments.

Devices that are described as in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. On the contrary, such devices need only transmit to each other as necessary or desirable, and may actually refrain from exchanging data most of the time. For example, a machine in communication with another machine via the Internet may not transmit data to the other machine for long period of time (e.g. weeks at a time). In addition, devices that are in communication with each other may communicate directly or indirectly through one or more intermediaries.

A description of an embodiment with several components or features does not imply that all or even any of such components/features are required. On the contrary, a variety of optional components are described to illustrate the wide variety of possible embodiments of the present invention(s). Unless otherwise specified explicitly, no component/feature is essential or required.

Although process steps, algorithms or the like may be described or claimed in a particular sequential order, such processes may be configured to work in different orders. In other words, any sequence or order of steps that may be explicitly described or claimed does not necessarily indicate a requirement that the steps be performed in that order. The steps of processes described herein may be performed in any order possible. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to the invention(s), and does not imply that the illustrated process is preferred.

Although a process may be described as including a plurality of steps, that does not imply that all or any of the steps are preferred, essential or required. Various other embodiments within the scope of the described invention(s) include other processes that omit some or all of the described steps. Unless otherwise specified explicitly, no step is essential or required.

Although a process may be described singly or without reference to other products or methods, in an embodiment the process may interact with other products or methods. For example, such interaction may include linking one business model to another business model. Such interaction may be provided to enhance the flexibility or desirability of the process.

Although a product may be described as including a plurality of components, aspects, qualities, characteristics and/or features, that does not indicate that any or all of the plurality are preferred, essential or required. Various other embodiments within the scope of the described invention(s) include other products that omit some or all of the described plurality.

An enumerated list of items (which may or may not be numbered) does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise. Likewise, an enumerated list of items (which may or may not be numbered) does not imply that any or all of the items are comprehensive of any category, unless expressly specified otherwise. For example, the enumerated list “a computer, a laptop, a PDA” does not imply that any or all of the three items of that list are mutually exclusive and does not imply that any or all of the three items of that list are comprehensive of any category.

An enumerated list of items (which may or may not be numbered) does not imply that any or all of the items are equivalent to each other or readily substituted for each other.

All embodiments are illustrative, and do not imply that the invention or any embodiments were made or performed, as the case may be.

V. Computing

It will be readily apparent to one of ordinary skill in the art that the various processes described herein may be implemented by, e.g., appropriately programmed general purpose computers, special purpose computers and computing devices. Typically a processor (e.g., one or more microprocessors, one or more microcontrollers, one or more digital signal processors) will receive instructions (e.g., from a memory or like device), and execute those instructions, thereby performing one or more processes defined by those instructions. Instructions may be embodied in, e.g., one or more computer programs, one or more scripts.

A “processor” means one or more microprocessors, central processing units (CPUs), computing devices, microcontrollers, digital signal processors, or like devices or any combination thereof, regardless of the architecture (e.g., chip-level multiprocessing/multi-core, RISC, CISC, Microprocessor without Interlocked Pipeline Stages, pipelining configuration, simultaneous multithreading).

Thus a description of a process is likewise a description of an apparatus for performing the process. The apparatus that performs the process can include, e.g., a processor and those input devices and output devices that are appropriate to perform the process.

Further, programs that implement such methods (as well as other types of data) may be stored and transmitted using a variety of media (e.g., computer readable media) in a number of manners. In some embodiments, hard-wired circuitry or custom hardware may be used in place of, or in combination with, some or all of the software instructions that can implement the processes of various embodiments. Thus, various combinations of hardware and software may be used instead of software only.

The term “computer-readable medium” refers to any medium, a plurality of the same, or a combination of different media, that participate in providing data (e.g., instructions, data structures) which may be read by a computer, a processor or a like device. Such a medium may take many forms, including but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media include, for example, optical or magnetic disks and other persistent memory. Volatile media include dynamic random access memory (DRAM), which typically constitutes the main memory. Transmission media include coaxial cables, copper wire and fiber optics, including the wires that comprise a system bus coupled to the processor. Transmission media may include or convey acoustic waves, light waves and electromagnetic emissions, such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD, any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, a RAM, a PROM, an EPROM, a FLASH-EEPROM, any other memory chip or cartridge, a carrier wave as described hereinafter, or any other medium from which a computer can read.

Various forms of computer readable media may be involved in carrying data (e.g. sequences of instructions) to a processor. For example, data may be (i) delivered from RAM to a processor; (ii) carried over a wireless transmission medium; (iii) formatted and/or transmitted according to numerous formats, standards or protocols, such as Ethernet (or IEEE 802.3), SAP, ATP, Bluetooth□, and TCP/IP, TDMA, CDMA, and 3G; and/or (iv) encrypted to ensure privacy or prevent fraud in any of a variety of ways well known in the art.

Thus a description of a process is likewise a description of a computer-readable medium storing a program for performing the process. The computer-readable medium can store (in any appropriate format) those program elements which are appropriate to perform the method.

Just as the description of various steps in a process does not indicate that all the described steps are required, embodiments of an apparatus include a computer/computing device operable to perform some (but not necessarily all) of the described process.

Likewise, just as the description of various steps in a process does not indicate that all the described steps are required, embodiments of a computer-readable medium storing a program or data structure include a computer-readable medium storing a program that, when executed, can cause a processor to perform some (but not necessarily all) of the described process.

Where databases are described, it will be understood by one of ordinary skill in the art that (i) alternative database structures to those described may be readily employed, and (ii) other memory structures besides databases may be readily employed. Any illustrations or descriptions of any sample databases presented herein are illustrative arrangements for stored representations of information. Any number of other arrangements may be employed besides those suggested by, e.g., tables illustrated in drawings or elsewhere. Similarly, any illustrated entries of the databases represent exemplary information only; one of ordinary skill in the art will understand that the number and content of the entries can be different from those described herein. Further, despite any depiction of the databases as tables, other formats (including relational databases, object-based models and/or distributed databases) could be used to store and manipulate the data types described herein. Likewise, object methods or behaviors of a database can be used to implement various processes, such as the described herein. In addition, the databases may, in a known manner, be stored locally or remotely from a device which accesses data in such a database.

Various embodiments can be configured to work in a network environment including a computer that is in communication (e.g., via a communications network) with one or more devices. The computer may communicate with the devices directly or indirectly, via any wired or wireless medium (e.g. the Internet, LAN, WAN or Ethernet, Token Ring, a telephone line, a cable line, a radio channel, an optical communications line, commercial on-line service providers, bulletin board systems, a satellite communications link, a combination of any of the above). Each of the devices may themselves comprise computers or other computing devices, such as those based on the Intel® Pentium® or Centrino™ processor, that are adapted to communicate with the computer. Any number and type of devices may be in communication with the computer.

In an embodiment, a server computer or centralized authority may not be necessary or desirable. For example, the present invention may, in an embodiment, be practiced on one or more devices without a central authority. In such an embodiment, any functions described herein as performed by the server computer or data described as stored on the server computer may instead be performed by or stored on one or more such devices.

Where a process is described, in an embodiment the process may operate without any user intervention. In another embodiment, the process includes some human intervention (e.g., a step is performed by or with the assistance of a human).

VI. Continuing Applications

The present disclosure provides, to one of ordinary skill in the art, an enabling description of several embodiments and/or inventions. Some of these embodiments and/or inventions may not be claimed in the present application, but may nevertheless be claimed in one or more continuing applications that claim the benefit of priority of the present application.

Applicants intend to file additional applications to pursue patents for subject matter that has been disclosed and enabled but not claimed in the present application.

VII. 35 U.S.C. § 112, Paragraph 6

In a claim, a limitation of the claim which includes the phrase “means for” or the phrase “step for” means that 35 U.S.C. § 112, paragraph 6, applies to that limitation.

In a claim, a limitation of the claim which does not include the phrase “means for” or the phrase “step for” means that 35 U.S.C. § 112, paragraph 6 does not apply to that limitation, regardless of whether that limitation recites a function without recitation of structure, material or acts for performing that function. For example, in a claim, the mere use of the phrase “step of” or the phrase “steps of” in referring to one or more steps of the claim or of another claim does not mean that 35 U.S.C. § 112, paragraph 6, applies to that step(s).

With respect to a means or a step for performing a specified function in accordance with 35 U.S.C. § 112, paragraph 6, the corresponding structure, material or acts described in the specification, and equivalents thereof, may perform additional functions as well as the specified function.

Computers, processors, computing devices and like products are structures that can perform a wide variety of functions. Such products can be operable to perform a specified function by executing one or more programs, such as a program stored in a memory device of that product or in a memory device which that product accesses. Unless expressly specified otherwise, such a program need not be based on any particular algorithm, such as any particular algorithm that might be disclosed in the present application. It is well known to one of ordinary skill in the art that a specified function may be implemented via different algorithms, and any of a number of different algorithms would be a mere design choice for carrying out the specified function.

Therefore, with respect to a means or a step for performing a specified function in accordance with 35 U.S.C. § 112, paragraph 6, structure corresponding to a specified function includes any product programmed to perform the specified function. Such structure includes programmed products which perform the function, regardless of whether such product is programmed with (i) a disclosed algorithm for performing the function, (ii) an algorithm that is similar to a disclosed algorithm, or (iii) a different algorithm for performing the function. Where there is recited a means for performing a function hat is a method, one structure for performing this method includes a computing device (e.g., a general purpose computer) that is programmed and/or configured with appropriate hardware to perform that function.

Also includes a computing device (e.g., a general purpose computer) that is programmed and/or configured with appropriate hardware to perform that function via other algorithms as would be understood by one of ordinary skill in the art.

VIII. Disclaimer

Numerous references to a particular embodiment does not indicate a disclaimer or disavowal of additional, different embodiments, and similarly references to the description of embodiments which all include a particular feature does not indicate a disclaimer or disavowal of embodiments which do not include that particular feature. A clear disclaimer or disavowal in the present application shall be prefaced by the phrase “does not include” or by the phrase “cannot perform”.

IX. Incorporation by Reference

Any patent, patent application or other document referred to herein is incorporated by reference into this patent application as part of the present disclosure, but only for purposes of written description in accordance with 35 U.S.C. § 112, paragraph 1 and enablement in accordance with 35 U.S.C. § 112, paragraph 1, and should in no way be used to limit, define, or otherwise construe any term of the present application where the present application, without such incorporation by reference, would not have failed to provide an ascertainable meaning, but rather would have allowed an ascertainable meaning for such term to be provided. Thus, the person of ordinary skill in the art need not have been in any way limited by any embodiments provided in the reference

Any incorporation by reference does not, in and of itself, imply any endorsement of, ratification of or acquiescence in any statements, opinions, arguments or characterizations contained in any incorporated patent, patent application or other document, unless explicitly specified otherwise in this patent application.

X. Prosecution History

In interpreting the present application (which includes the claims), one of ordinary skill in the art shall refer to the prosecution history of the present application, but not to the prosecution history of any other patent or patent application, regardless of whether there are other patent applications that are considered related to the present application, and regardless of whether there are other patent applications that share a claim of priority with the present application.

Demographic

As used herein, the term demographic may refer to an age, age range, race, gender, income level, range of income levels, marital status, level of education, presence or absence of children, number of children, net worth, language spoken, religion, political orientation, or to any other characteristic which may be used to classify a person into some segment of the population.

House Edge, House Advantage

As used herein, the terms “house edge” and “house advantage” may refer to an amount that the house is expected to retain, on average, per unit bet by the player. The house edge may be expressed in percentage terms. For example, a house edge of 5% may indicate that the house can expect to retain 5 cents on average per dollar bet by a player. It should be noted that a statement of a house edge does not imply that the house will necessarily retain the stated amount of a player's bet on each game. The house edge, rather, refers to an expectation or average. For example, suppose a player bets 1 on a game in which he has a 45% chance of winning 2, and a 55% chance of winning nothing. The house edge may be calculated as (0.55*(0)+0.45*(2))/1=10%. Thus, the house may expect to win 10 cents per dollar wagered by the player.

Outcome

As used herein, the term “outcome” may refer a set of symbols or indicia which may be obtained (e.g., randomly generated; e.g., selected by a player) in a game (e.g., in a game played with a wager), and which may determine a course or direction in the game and/or which may determine a payment or prize to be awarded from the game. The term “outcome” may, in various embodiments, refer both to symbols and indicia and to the payment or prize awarded in a game. The term “outcome” may, in various embodiments, refer to the prize or payment awarded in a game. In various embodiments, multiple outcomes may occur during a game. For example, in a slot machine game, each activated pay-line may feature a different outcome. Further, in various embodiments, a game may include a succession of outcomes. For example, in a game of video poker, an initial set of five cards dealt to a player may constitute a first outcome. The final hand of cards obtained by the player after discarding cards from the initial set of five cards may constitute a second outcome. In various embodiments, the aggregate effect of several outcomes in a game may itself constitute an outcome. For example, in a slot machine game, a player may activate three pay-lines and may thereby receive three outcomes. Payouts associated with the three outcomes may be 2 coins, 5 coins, and 3 coins. Thus, the aggregate outcome of the game may be that the player receives a payout of 10 coins. Examples of outcomes include: (a) a set of symbols achieved across the pay-line of a reel slot machine; (b) a set of cards dealt in a game of poker; (c) a set of cards dealt in a game of blackjack; (d) a player hand in a game of blackjack; (e) a player hand in combination with a dealer hand in blackjack (i.e., an outcome in a game of blackjack may include cards received by a player and cards received by a dealer); (f) a number rolled in a game of craps; (g) a series of numbers rolled in a game of craps (e.g., in a game of craps, an outcome may include the entire series of numbers rolled between the time a player made a bet and the time the player was paid for his bet or lost his bet); (g) a set of numbers generated in a game of keno; (h) a prize amount revealed in a bonus round; and so on.

Product

As used herein, the term “product” may include a good. As used herein, the term “product” may include a service.

Gaming

As used herein, the term “gaming” may refer to placing a first value at risk on one or more events whose outcomes cannot be predicted with certainty, with the possibility of winning a second value should a particular outcome of the event(s) actually occur. Gaming may include: (a) betting money on the outcome of a roll of dice; (b) betting money on the deal of one or more cards; (c) betting money on the spinning of a wheel; (d) betting money on the spinning of slot machine reels; (e) betting money on the outcome of a sporting contest; (f) betting money on the outcome of an election; (g) betting money on the occurrence of a natural event, such as a hurricane; and betting money on any other event which cannot be predicted with certainty. Gaming may include: (a) playing a game of poker with money at risk; (b) playing a game of craps with money at risk; (c) playing a game of roulette with money at risk; (d) betting money on the outcome of a football game; or betting money on any other game or contest. The “value” placed at risk in gaming may include anything that may be of benefit to a person or other entity, whether or not the benefit may be experienced by the person engaging in gaming value may be tangible or intangible. Value may include: (a) cash; (b) credits; (c) tokens; (d) rights (e.g., the right to bypass a line for a buffet; e.g., the right to a free spin at a slot machine); (e) products; (f) services; (g) comp points; (h) coupons; (i) vouchers; (j) movie tickets; (k) the right to receive a loan; (l) frequent flyer miles; and any other item of value. The value that may be won from gaming need not be of the same type as that placed at risk. For example, a person may put at risk cash in order to win movie tickets. The events which are the subject of gaming may be predictable in principle, but may not be predictable given applicable rules, standards, or capabilities. For example, a person may be able to predict which cards will be dealt by rigging a deck of cards. However, rigging the deck of cards would be contrary to the rules of the game. Placing an item of value at risk may include allowing the possibility that some or all of the item of value will be lost. Gaming may include placing value at risk even if such value is not in the possession of the gamer. For example, a business owner may bet half of his future business profits for the forthcoming calendar year. Gaming may include investing, such as investing in the stock or bond market. Gaming may further include taking a derivative position, such as buying puts or calls on stocks.

Detection of One Device by Another

Various embodiments described herein may refer to the interaction between a first device and a “nearby” second device. In various embodiments, the first device may take action if the second device is nearby. In various embodiments, the second device may take action if the first device is nearby. When terms such as “nearby”, “near”, “close”, “proximate”, “presence”, or the like are used, it will be understood that the first device may recognize the presence of the second device in various ways, that the second device may recognize the presence of the first device in various ways, that the first device may react to the presence of the second device in various ways, and that the second device may react to the first device in various ways. It may be noted that the first device may react to the presence of the second device without recognizing the presence of the second device if, for example, the first device is instructed to take an action by a third device which recognizes that the second device is near to the first device. In various embodiments, the first device and/or the second device may be in motion. For example, the first device may be moving (e.g., the first device may be carried by a walking person) while the second device may be stationary.

Various technologies may allow a first device to recognize and/or to react to the presence of a second device. Various technologies may allow a second device to recognize and/or to react to the presence of a first device. As used herein, the term “beacon” includes a device which generates a signal which may be used as a reference signal by another device or person, e.g., so that the other device may determine its own location or position. A beacon may emit a continuous, periodic, sporadic, or other type of signal. A beacon may emit a directed signal (e.g., a signal which is most easily detected by devices at a certain incident angle to the beacon) or the beacon may emit a signal of equal strength in all directions. A beacon may emit a signal when triggered by the presence of another device, or may emit a signal independently of other events. A beacon may have, as its sole function, the broadcast of a reference signal. A beacon may serve as a beacon only incidentally. For example, a light bulb may incidentally serve as a beacon even though its primary purpose may be to light a room. A beacon may be natural (e.g., the sun) or man-made. A beacon may emit light, sound, radio waves, microwaves, odors, or any other form of signals.

-   -   Radio Frequency Identification (RFID) tags or transponders are         devices, generally small, that can transmit signals and/or         redirect signals, and use such signals as a means for providing         identification. The transmitted or redirected signals are         generally radio waves. Signals which are transmitted or         redirected may contain a unique signature or pattern, which may         serve to uniquely identify the RFID tag. If the tag is         associated with a device (e.g., by attachment or by         incorporation into the device), then the unique identification         of the tag can, by association, serve to uniquely identify the         device.     -   Near field communication (NFC) is a technology that allows for         secure wireless communication over short distances, typically in         the range of inches. An exemplary application has been tested by         Motorola and Mastercard, in which cellular phones are outfitted         with NFC to allow for credit card payments using cellular         phones.     -   Infrared data transmission can be used as a means of         communication between two nearby devices. For example, an         infrared light-emitting diode (LED) can be used to generate         signals. The signal pattern can be created by switching the LED         on and off. A receiver may include a silicon photodiode, which         may convert incident infrared light into electrical signals.         Infrared signals may also be transmitted with lasers.     -   A device may be recognized by means of a captured picture or         image of the device. For example, a first device may take a         picture of a second device. The first device may use image         processing algorithms to detect salient features of the second         device. For example, if the second device has a pattern of black         and white stripes, then the first device may search for such a         pattern within captured images.     -   One or more devices may use positioning technologies to         determine their own location. Once the locations of two devices         are known, simple algorithms may be used to determine whether         the devices are close to one another or not. For example, the         distances between two devices with known x and y coordinates can         be at least approximated using the Pythagorean Theorem. Various         positioning technologies may be used. For example, a device may         receive a signal from a beacon or other signal generator of a         known location. Particularly if the beacon has a short range,         the device's position may be assumed to approximate the position         of the beacon. In various embodiments, a device may receive         signals from multiple beacons or signal generators. The signal         generators may coordinate to transmit the signals         simultaneously. However, depending on the device's location, the         device will not necessarily receive the signals from all the         beacons at the same time. For example, if the device is closer         to beacon 1 than to beacon 2, the device will receive the signal         from beacon 1 prior to receiving the signal from beacon 2. Based         on the arrival times of signals from the various beacons, the         device's location may be deduced. For example, geometric or         trigonometric algorithms may be used to determine the location         of the device based on the known locations of the beacons and         based on the arrival times of simultaneously transmitted signals         from the beacons. In an analogous fashion to systems involving         beacons, positioning systems may make use of receivers at known         locations (e.g., fixed receivers). The fixed receivers each         receive a signal from the device about which a location is         desired. The same signal from the device might arrive at the         different receivers at different times, or from different         angles. Based on the arrival times or angles of arrival of the         signal at the various receivers, algorithms may be used to         determine the location of the device. Exemplary positioning         systems are as follows:         -   The Global Positioning System (GPS) is based on a             constellation of satellites which transmit reference signals             to locations on earth. GPS receivers can pick up reference             signals from multiple satellites and use the signals to             determine a position and/or an altitude.         -   Long Range Navigation (LORAN) is a navigation based on             earth-based radio transmitters. The location of a device can             be estimated based on differences in arrival times at the             device of signals from three or more transmitters.         -   Radiolocation using the cellular telephone network is a             system whereby cellular base stations serve as fixed             receivers. The signal from a cellular phone may be received             at multiple base stations. The location of the cellular             phone may be determined based on when a signal from the             cellular phone was received at each of the base stations,             based on the angle with which a signal from the cell phone             was received at each of the base stations, and/or based on             characteristic distortions in the cell phone signal that             would indicate a particular location of origin of the             signal.     -   A first device may emit an audio signal. The audio signal may         consist of a distinct series of notes or pulses. A second device         may pick up the audio signal using a microphone, for example.         The second device may recognize the distinctive pattern of the         audio signal and may thereby deduce the presence of the first         device. In a similar fashion, the second device may emit an         audio signal which may allow the first device to identify the         second device.     -   A first device may recognize the presence of a second device         from physical or electronic contact. For example, a first device         may have a port where a second device can be docked. When         docked, the second device may come into electrical contact with         the first device. The first device may thereby recognize the         presence of the second device and/or the second device may         thereby recognize the presence of the first device.

There are various ways in which one or more devices may detect the presence of one or more other devices. There are various ways in the proximity of two devices may be determined.

-   -   A first device may detect a signal from a second device. The         first device may thereby detect the presence of the second         device.     -   A first device may determine its own location. For example, the         first device may use a positioning system to determine its own         location. The first device may already know the location of the         second device. For example, the second device may be at a         well-known, fixed location. The first device may have stored in         memory the location of the second device. Once the first device         knows its own location and that of the second device, the first         device may deduce (e.g., using geometric algorithms) when the         first device is near to the second device.     -   A third device may detect the position of a first device, e.g.,         using a positioning system. The third device may know the         position of a second device. The third device can then inform         the first, second, or both devices of the positions of either or         both of the first and second devices. The first device may         thereby determine whether it is proximate to the second device.         The second device may thereby determine whether it is proximate         to the first device. In some embodiments, the third device may         inform the first device that the first device is near the second         device. In some embodiments, the third device may inform the         second device that it is near the first device. In some         embodiments, the third device may instruct the first device to         take some action based on the fact that the first device is near         to the second device, without necessarily informing the first         device that the first device is near the second device. In some         embodiments, the third device may instruct the second device to         take some action based on the fact that the second device is         near to the first device, without necessarily informing the         second device that the second device is near the first device.     -   A third device may detect the positions of both a first device         and a second device. The third device can then inform the first,         second, or both devices as above. That is, the third device may         inform the first and/or second devices of the first and/or         second devices' positions or of the fact that the first and         second devices are near to each other. The third device may also         provide instructions to the first and/or to the second device         based on the fact that the two devices are near to each other.     -   A third device may detect the position of a first device. A         fourth device may detect the position of a second device. The         third and fourth devices may then inform the first device of         both positions. The third and fourth devices may inform the         second device of both positions. The third and fourth devices         may inform the first device that the first device is near the         second device. The third and fourth devices may inform the         second device that the first device is near the second device.         The third and/or fourth devices may instruct the first device to         take some action based on the fact that the first device is near         the second device. The third and/or fourth devices may instruct         the second device to take some action based on the fact that the         first device is near the second device. The fourth device may         inform the third device of the position of the second device.         The third device may inform the first device of the positions of         the first device and the second device. The third device may         inform the first device that the first device is near the second         device. The third device may inform the first device to take         some action based on the fact that the first device is near the         second device. The third device may inform the second device of         the positions of the first device and the second device. The         third device may inform the second device that the first device         is near the second device. The third device may inform the         second device to take some action based on the fact that the         first device is near the second device.     -   A third device may detect the position of a first device. A         fourth device may detect the position of a second device. The         third and fourth devices may inform a fifth device of both         positions. The fifth device may inform the first and/or second         devices of both positions. The fifth device may inform the first         device that it is near to the second device. The fifth device         may inform the second device that it is near to the first         device. The fifth device may instruct the first device to take         some action based on the fact that the first device is near the         second device. The fifth device may instruct the second device         to take some action based on the fact that the second device is         near the first device.         Transmission and Communication

Various embodiments described herein describe the “transmission” or “communication” of a digital or electronic composition, such as a digital image, a text file, a computer program, an audio file, a video file, or any other object or entity. Transmission or communication of a digital or electronic composition may include transmission of data such that the data alone is sufficient to entirely reconstruct the composition. For example, the transmission of a digital image may include the transmission of one million bytes of data, each byte characterizing one of the pixels in the digital image, such that the digital image may be completely reconstructed from the data alone. Transmission or communication of a digital or electronic composition may include transmission of a data such that the transmitted data may be used in combination with other data to reconstruct the composition. For example, a digital image may be transmitted in a compressed format. The data that is transmitted may be used in combination with data describing a decompression algorithm in order to reconstruct the digital image. Transmission or communication of a digital or electronic composition may include transmission of a data which indicates or characterizes the composition such that the composition can be retrieved or acquired elsewhere. For example, data describing the title of an image may be communicated from a first device to a second device. The second device may have various images already stored on the second device and indexed by title. The second device may reconstruct the image that was communicated from the first device by using the title to retrieve a complete description of the second image from storage on the second device.

In various embodiments, transmission or communication of a promotion may include transmission or communication of a digital or electronic composition.

Encode

As used herein, a signal that “encodes” a digital or electronic composition may include sufficient data to reconstruct the composition from the data alone. For example, a signal that encodes an advertisement consisting of an image may include data which is sufficient, on its own, to reconstruct the image.

As used herein, a signal that “identifies” a digital or electronic composition may include data that provides information indicating where or how the composition may be retrieved. A signal that identifies a digital or electronic composition may include data that provides a name, title, or other identifier for the composition such that the composition can be retrieved from a database or other storage medium using the name, title or other identifier.

Encryption

As used herein, the term “encryption” may refer to a process for obscuring or hiding information so that the information is not readily understandable without special knowledge. The process of encryption may transform raw information, called plaintext, into encrypted information. The encrypted information may be called ciphertext, and the algorithm for transforming the plaintext into ciphertext may be referred to as a cipher. A cipher may also be used for performing the reverse operation of converting the ciphertext back into plaintext. Examples of ciphers include substitution ciphers, transposition ciphers, and ciphers implemented using rotor machines.

In various encryption methods, ciphers may require a supplementary piece of information called a key. A key may consist, for example, of a string of bits. A key may be used in conjunction with a cipher to encrypt plaintext. A key may also be used in conjunction with a cipher to decrypt ciphertext. In a category of ciphers called symmetric key algorithms (e.g., private-key cryptography), the same key is used for both encryption and decryption. The sanctity of the encrypted information may thus depend on the key being kept secret. Examples of symmetric key algorithms are DES and AES. In a category of ciphers called asymmetric key algorithms (e.g., public-key cryptography), different keys are used for encryption and decryption. With an asymmetric key algorithm, any member of the public may use a first key (e.g., a public key) to encrypt plaintext into ciphertext. However, only the holder of a second key (e.g., the private key) will be able to decrypt the ciphertext back in to plaintext. An example of an asymmetric key algorithm is the RSA algorithm.

It will be appreciated that other methods besides encryption may be used to hide or obscure information, such as encoding or steganography. Such methods may also be used in conjunction with cryptography.

Encryption may be used to:

-   -   Send a message only specific recipients can read. For example,         Alice and Bob may both be in possession of the same secret key.         Alice may encrypt a plaintext message with the secret key. She         may transmit the resultant ciphertext to Bob. Bob may then         decrypt the cyphertext using the secret key so as to view the         plaintext version of the message.     -   Allow messages to be encrypted by many and decrypted only one         (e.g., PGP). For example, Alice may possess a public and a         private key. Bob may wish to send Alice a message that only         Alice will be able to read. Bob may create a message in         plaintext and encrypt it using Alice's public key. Bob may send         the resultant ciphertext to Alice. Alice may then decrypt the         ciphertext using her private key, and may thereby view the         plaintext message. Should Cindy intercept the ciphertext message         on its way from Bob to Alice, Cindy would not be able to decrypt         the message since Cindy would not have access to Alice's private         key. Alice's public key, although available to Cindy, would not         be sufficient to decrypt the ciphertext message in a practicable         amount of time.     -   Authenticate the sender of a message. This use of encryption may         include having the sender create a digital signature. For         example, Alice would like to send a message to Bob in such a way         that Bob can be confident that the message has come from her.         Alice may construct a plaintext message and encrypt the         plaintext into ciphertext using her private key. Alice may then         send the ciphertext message to Bob. Bob may then use Alice's         public key to decrypt the ciphertext back in to plaintext. Since         Alice's public key only works to decrypt a ciphertext message         created using Alice's private key, and since presumably only         Alice has access to her own private key, Bob can be confident         that the message originated from Alice.     -   Allow for non-repudiation. If a sender has applied a digital         signature to a message, or portion of a message, then the sender         will not later be able to claim he did not send the message.     -   Guarantee a time/data sent. See hashing below.     -   Guarantee receipt by recipient. See hashing below.     -   Verify that a message has not been altered after being sent by         the sender. See hashing below.

Hashing is a process whereby input data, typically of arbitrary length, is transformed into output data, typically of shorter length and/or of fixed length. A hash function is a function that performs the transformation. Often, useful hash functions will be one-way functions. That is, for a given input, the output can be computed readily. However, for a given output, the input which produced the output will be difficult to calculate. Also, useful hash functions will often have the property that two differing inputs rarely produce the same output. Hashing can be used for the following purposes:

-   -   To perform data redundancy checks. For example, a database may         contain a large number of names. The names may be of arbitrary         length. To check for redundant names, hash values for the names         may be created. The hash values may be of smaller size than the         names and may all be of the same length. Thus, it may be easier         to compare the hash values of the names that it will be to         compare the names themselves.     -   To verify that a message has not been altered. For example,         Alice can send a plaintext message to Bob along with a hash         value of the message. Alice can apply a digital signature to the         hash value so as to assure Bob that the hash value has been sent         by Alice. When Bob receives the plaintext message from Alice,         Bob can compute the hash value of the message. If the hash value         that Bob computes is the same as the hash value that Alice has         sent to Bob, then Bob can be fairly confident that the message         has not been altered en route from Alice to Bob.     -   To prove possession of a message without having to reveal the         message. For example, Alice can send a message to Bob. Bob can         take the hash of the message and send it back to Alice. Alice         may thus be assured that Bob has the message without the risk of         the message being intercepted en route from Bob to Alice.     -   To prove possession of a message at a certain time without         having to reveal the message. For example, Alice might have a         great idea and wish to prove she came up with it at a certain         time without having to reveal the idea. Thus, Alice might write         out the idea in the form of text, and take a hash value of the         text. Alice can then publish the hash of the text in a         newspaper. It will then be readily apparent that Alice had         possession of the idea at least on the date of the newspaper's         publication.     -   To timestamp a document. For example, a document may be sent to         a time-stamping service. The service may then determine the hash         value of the document. The service may append the then current         date and time to the hash value of the document and apply a         digital signature to the result. The digitally signed hash value         plus date and time may then be published. So long as the         time-stamping service can be trusted to provide accurate dates         and times (e.g., not to use old dates and times) then the         published timestamp may serve as proof that the document was in         existence as of the date and time provided by the time-stamping         service. Further precautions may ensure that it becomes very         difficult for even the time-stamping service to provide fake         times and dates. For example, the time-stamping service may add         a sequence number, (e.g., 1, 2, 3, etc.) to each document it         timestamps. If the service wishes to provide an old date, the         service would have to find an older sequence number. The older         sequence number would have to fit between two sequence numbers         used immediately before and immediately after the desired fake         date. However, no such sequence number would be available if,         e.g., no numbers had been skipped in the first place.

FIG. 1 shows a system 100 according to some embodiments. In various embodiments, the system may function within the confines of a casino. In various embodiments, the system may function within the confines of a casino and associated areas, such as retail shops, exercise rooms, restaurants, swimming areas, showrooms, conference halls, and so on. In various embodiments, the system may function beyond the confines of a casino. A casino server 105 may be in communication with one or more mobile gaming devices, such as devices, 110, 115, and 120. The casino server may be in communication with one or more marketer devices, such as marketer device 125. Marketer devices may transmit information to the casino server include information describing promotions to run (e.g., graphics and audio associated with promotions), when to run the promotions, what players should view promotions, what price will be paid for running promotions, what media to use for running promotions (e.g., symbols; e.g., background areas of a displays screen) and so on. The casino server 105 may be in communication with one or more display devices, such as display device 130. Display devices may include billboards, electronic signs, signs, television monitors, projectors, or other display devices. The casino server may instruct a display device to display graphics associated with a promotion, in various embodiments. The casino server may be in communication with one or more receivers, such as receiver 135. Receivers may include antenna, RFID tag readers, bar code readers, and so on. Receivers may detect signals emitted from mobile gaming devices. Receivers may use such signals to determine the location of the mobile gaming devices. Receivers may also receive data from mobile gaming devices. Such data may be relayed to the casino server. The casino server 105 may be in communication with one or more beacons, such as beacon 140. Beacons may form part of a positioning system which may be used by mobile gaming devices to determine their positions. For example, beacons may emit signals within a casino. A mobile gaming device, by receiving signals from several beacons, may be able to triangulate its own position within the casino. The casino server 105 may be in communication with one or more gaming devices, such as gaming device 145. Gaming devices may include slot machines, video poker machines, video blackjack machines, video keno machines, and so on. The casino server may be in communication with one or more point of sale (POS) terminals, such as POS terminal 150. POS terminals may include any terminals associated with retail establishments, or any other terminals that can handle sales transactions. In various embodiments, a POS terminal may determine an appropriate promotion to be displayed on a nearby mobile gaming device. The POS terminal may transmit the promotion to the casino server. The casino server may, in turn, transmit the promotion to the mobile gaming device.

FIG. 2 shows a mobile gaming device 110 according to some embodiments.

XI. Embodiments

-   1. Types of promotion. In various embodiments, promotions may be     presented using mobile gaming devices. A promotion may include: (a)     an advertisement (e.g., for a product or service); (b) an     announcement (e.g., an announcement as to when a new show is     starting at a casino; e.g., an announcement that a certain car was     rated number one in the country); (c) a warning (e.g., a warning     about the approach of inclement weather); (d) a statement of     information (e.g., candidate Jones has just won the election); (e)     an offer of a benefit (e.g., an offer of a discount; e.g., an offer     of a coupon; e.g., an offer of a gift certificate); (f) an offer of     a benefit in exchange for some action on the part of the recipient     of the offer (e.g., an offer of a gift certificate in exchange for     the recipient of the offer answering survey questions); (g) a     request (e.g., a request to answer survey questions); (h) a benefit     given unconditionally (e.g., cash given unconditionally; e.g., a     gift certificate given unconditionally); (i) an entry into a     sweepstakes or other chance event (e.g., an entry into a drawing for     a particular merchant's car); (j) a personalized advertisement     (e.g., an advertisement that includes a name or other information     about a target), and so on. Promotions may be presented in various     forms and in various situations. Promotions may be presented in     audio form, video form, or text form, for example. Promotions may be     presented at various points in time relative to other events. For     example, promotions may be presented in between games played on a     mobile device.     -   1.1. Audio. Promotions may be presented in audio form. A         promotion may include a spoken voice. For example, an announcer         or narrator may describe the features of a product that is being         advertised. A promotion may include a song. A promotion may         include a musical tune. A promotion may include a sound track,         such as the revving of a motorcycle engine. A promotion may         include a jingle, such as a jingle commonly associated with a         product. Some promotions may be broadly directed at an area         (e.g., an area of a casino in which a number of people targeted         by the advertisement are located) and audio may accordingly be         broadly directed at that area (e.g., through speakers in a         casino). Other promotions may be narrowly directed at a target         (e.g., at a single person or a small group of people) and audio         accordingly may be narrowly focused (e.g., using hypersonic         sound, using a mobile device speaker, using a speaker from a         nearby gaming device).     -   1.2. Text. A promotion may include text. Text may include         information, slogans, personal information, or subtitles, for         example.     -   1.3. Still image. A promotion may include still images. The         image may take up all or part of a display screen, such as the         display screen on the mobile gaming device. The image may         represent an actual photograph, an image created by an artist,         or an image created by a computer, for example.     -   1.4. Video. A promotion may include video. The video may be         comprised of a sequence of still images, for example. The video         may occupy an entire display screen or part of a display screen,         for example. A video may be the product of a camera, or may be         an animation, for example.     -   1.5. Vibration. A promotion may include vibration, or any         induced motion of the mobile gaming device. For example, the         mobile gaming device may vibrate in conjunction with a promotion         for a car race, where the vibrations may help the player of the         mobile gaming device to imagine the cars rumbling by.     -   1.6. Flashing lights. A promotion may include flashing or         blinking lights. For example, light emitting diodes (LEDs) on         the mobile gaming device may flash in order to convey excitement         associated with a promotion.     -   1.7. Smells. A promotion may include smells. For example, a         mobile gaming device may release small quantities of chemicals         to create aromas in conjunction with a food advertisement.     -   1.8. Trigger nearby signs or slot machines to display         advertisements. In some embodiments, a promotion may include a         signal to other displays or devices, the signal instructing such         displays or devices to participate in the promotion. For         example, as part of a promotion, a mobile gaming device may send         a signal to a nearby slot machine (e.g., to a slot machine         located within hearing range; e.g., to a slot machine located         within a line of sight of the mobile gaming device) instructing         the slot machine to perform one or more actions related to the         promotion. In some embodiments, a mobile gaming device may         instruct a slot machine to generate an audio output. For         example, the mobile gaming device may instruct that the slot         machine blast the sounds of bells ringing through a speaker that         is part of the slot machine. In some embodiments, a mobile         gaming device may a slot machine to generate a video output. For         example, the mobile gaming device may instruct a slot machine to         show a particular video or animated clip. In some embodiments, a         mobile gaming device may instruct a slot machine to show an         image. For example, a mobile gaming device may instruct a slot         machine to show an image of a product being promoted by the         mobile gaming device. It should be recognized that in other         embodiments, the mobile device may not be the initiator of         promotions, but rather a centralized system may determine where         and when to display promotions (e.g., on the mobile device and         on other devices or displays).         -   1.8.1. Distances. In various embodiments, a slot machine,             another gaming device, a display screen, or any other device             may participate in presenting a promotion so as to enhance             the effect of a promotion. For example, a promotion may be             more effective if five slot machines surrounding a player             all show the same sounds and images than if only the display             screen on the mobile gaming device is involved. A promotion             may be particularly effective, in some embodiments, if             participating slot machines or other devices can influence             the player of the mobile gaming device. Thus, particularly             effective devices may include devices that are visible or             audible to the player. In various embodiments, a device is             instructed to participate in a promotion if the device is             within a certain range of a mobile gaming device. For             example, a mobile gaming device may instruct a slot machine             to participate in a promotion if the slot machine is within             ten feet of the mobile gaming device. In various             embodiments, a mobile gaming device may instruct a device to             participate in a promotion if: (a) the device is within a             predetermined distance of the mobile gaming device; (b) if             the device is within a direct line of sight of the mobile             gaming device (e.g., if there are no other devices or             fixtures between the mobile gaming device and the             device); (c) the device is in the same room as the mobile             gaming device; (d) the device is on the same floor of a             building as is the mobile gaming device; (e) the device is             facing at least somewhat towards the mobile gaming device             (e.g., the mobile gaming device may only request that a slot             machine participate in a promotion if the screen of the slot             machine is facing in the direction of the mobile gaming             device); (f) the mobile gaming device can detect a signal             from the device (e.g., a gaming device may emit a short             range signal that is detectable by the mobile gaming device             only if the mobile gaming device is within proximity to the             gaming device; (g) the device can detect a signal from the             mobile gaming device; (h) the mobile gaming device receives             a signal from the device at a certain minimum threshold             power (e.g., if the signal power is strong in the detected             signal, the device may be assumed to be near to the mobile             gaming device); (i) the device receives a signal from the             mobile gaming device at a certain minimum threshold power             level; (j) if the device has video display capability; (k)             if the device has audio output capability; (l) if the device             has speakers of a certain minimum output capability; and so             on. In various embodiments, a mobile gaming device may             determine whether or not another device is available for             participation in a promotion. Another device may be             available if such device: (a) is currently not participating             in a different promotion (e.g., if the device is not             displaying graphics as part of a promotion to a different             player); (b) is currently not being used for gaming purposes             (e.g., a slot machine may be available if it is not             currently being played by another player); (c) is currently             not being used for other purposes (e.g., a plasma display             monitor may be available if it is not currently not             broadcasting programming to passing people); (d) is             functioning (e.g., if the device is not experiencing             mechanical or electrical problems); (e) is not scheduled or             intended for immediate use; (f) is not restricted from             participating in promotions of the type in which the device             would be asked to participate in (e.g., a device made by a             first manufacturer may be restricted from promoting products             from a competing manufacturer); and so on. In various             embodiments, a device that may be instructed to participate             in a promotion may include a slot machine, video poker             machine, another gaming device, a display monitor (e.g., a             plasma display screen; e.g., a cathode ray tube (CRT)             monitor), a billboard, a projection display, a speaker, a             public address system output, a light bulb, a light fixture,             and so on.             -   In various embodiments, a device may be proximate to                 several players with mobile gaming devices. For example,                 a slot machine may be within 10 feet of each of three                 players of mobile gaming devices. Such players may                 coincidentally happen to be in the same area, for                 example. The three mobile gaming devices (those                 belonging to each of the three players) may cooperate to                 schedule the same promotion at the same time so that the                 device which is proximate to all three players may show                 a promotion which influences all the three players at                 once. For example, each of the three mobile gaming                 devices may schedule an advertisement for cruise                 vacations to occur at the same time. As the mobile                 gaming devices broadcast audio to the three players, the                 slot machine which is near to all three players may show                 a video of a cruise ship sailing through blue waters and                 stopping at tropical islands.             -   In various embodiments, a plurality of mobile gaming                 devices may coordinate to schedule the same or similar                 promotions at the same time. A device which can                 influence the players of the mobile gaming devices may                 be commanded or requested to participate in the                 promotion. The device may be a slot machine, TV monitor,                 billboard, or any other device. The device may,                 accordingly, broadcast sounds images, or other                 information in support of the promotion. The device may                 be selected or chosen because it is within a certain                 distance of all of the mobile gaming device players,                 because it is within line-of-site of all of the mobile                 gaming device players, because it is within hearing                 range of all the mobile gaming device players, and/or                 for any other reason. In various embodiments, a device                 (e.g., a slot machine) may be selected to participate in                 a promotion that is being presented to a plurality of                 players even though the device may be unable to                 influence one of the plurality of players. For example,                 a slot machine may be chosen to participate in a                 promotion being presented to several players even if one                 of the players cannot see the screen of the slot                 machine.             -   In various embodiments, a device may have the potential                 to participate in two or more promotions at a given                 time. For example, a first player of a mobile gaming                 device and a second player of a mobile gaming device may                 each be in proximity to the device. Various criteria may                 be use to determine whether the device will participate                 in a promotion presented to the first player or the                 second player. The device may participate in the                 promotion presented to the first player if: (a) the                 first player is in closer proximity to the device than                 is the second player; (b) the first player has a better                 view of the device than does the second player (e.g., a                 display screen of the device is facing towards the first                 player but away from the second player); (c) the first                 player is deemed more likely to be influenced by the                 promotion than is the second player; (d) the first                 player is a better customer of the casino than is the                 second player (e.g., the first player has bet more money                 at the casino in the past than has the second                 player); (e) the second player is a better customer of                 the casino than is the first player; (f) the first                 player is deemed more likely to pay attention to the                 device participating in the promotion; (g) the first                 player has shown more interest in the product scheduled                 to be promoted to the first player than has the second                 player shown in the product scheduled to be promoted to                 the second player; (h) the second player is in proximity                 to another device which might participate in the                 promotion scheduled to be presented to the second                 player; and/or if other criteria are satisfied. It will                 be appreciated that similar criteria may be used to                 choose which promotion a device (e.g., a slot machine)                 will participate in given that three or more players of                 mobile devices are in the vicinity. In some embodiments,                 a device (e.g., a slot machine) may participate in a                 promotion if such promotion will be presented to the                 majority (or the plurality) of the players of mobile                 gaming devices which are in the vicinity of the device.         -   1.8.2. Sending the signals. The determination of whether or             not it would be appropriate for a device (e.g., a slot             machine) to participate in a promotion of a mobile gaming             device may be determined in various ways. In some             embodiments, the mobile gaming device may detect the             presence of the device (e.g., the slot machine). The mobile             gaming device may detect the presence of the device by             detecting a signal emitted from the device. The signal may             be caused by radio frequency identification (RFID) tag             associated with the device. The signal may be an infrared             signal or any other signal. In some embodiments, the device             (e.g., the slot machine) may detect the presence of the             mobile gaming device. The device may detect a signal from             the mobile gaming device, such as a signature of an RFID tag             associated with the mobile gaming device, such as an             infrared signal from the mobile gaming device, or any other             signal. In various embodiments, the device (e.g., the slot             machine) may detect the presence of the mobile gaming device             using optical means. For example, the device may include a             camera and may employ image processing algorithms to             recognize when a player in the vicinity of the gaming device             is carrying a mobile gaming device. In various embodiments,             the mobile gaming device may contain a positioning system,             such as a global positioning system (GPS). The mobile gaming             device may determine based on its position whether it is             currently proximate to a device (e.g., a slot machine). For             example, the mobile gaming device may access an internally             stored map describing the positions of one or more devices.             In various embodiments, the mobile gaming device and/or the             device (e.g., the slot machine) may relay any received             signals to a central server. For example, the device (e.g.,             the slot machine) may relay signals from the mobile gamine             device to the central server. The central server may             recognize that the signals were generated by the mobile             gaming device. Therefore, the central server may recognize             that the mobile gaming device is likely in proximity to the             device (e.g., the slot machine). Similarly, the mobile             gaming device may relay signals from the device (e.g., the             slot machine) to the central server. The central server may             recognize such signals as originating from the device (e.g.,             the slot machine) and may thereby recognize that the mobile             device is in proximity to the device (e.g., the slot             machine). In various embodiments, one or more sensors may             detect the presence of the mobile gaming device via signals             emitted or transmitted from the mobile gaming device. The             sensors may not be associated with a device (e.g., with a             slot machine). The sensors may be in communication with the             central server. Thus, using signals detected from sensors,             and possibly using triangulation or other location             algorithms, the central server may detect the presence of             the mobile gaming device. The central server may be informed             or otherwise detect the position of other devices (e.g.,             slot machines, displays, etc.) and may use such information             along with the detected position of the mobile gaming device             to control where to display promotions.             -   In various embodiments, once the central server                 recognizes that a mobile gaming device is in proximity                 to a device (e.g., a slot machine), the central server                 may arrange for the device to participate in a promotion                 to be presented by the mobile gaming device. For                 example, the central server may instruct both the mobile                 gaming device and the device (e.g., the slot machine) to                 present a promotion at the same time. For example, the                 mobile gaming device may present an audio and a video                 portion of a promotion while the nearby device (e.g.,                 the slot machine) may present a video sequence as part                 of the promotion. In various embodiments, when the                 central server recognizes that a mobile gaming device                 and a device (e.g., a slot machine) are in proximity,                 the central server may determine whether it is                 appropriate that the device (e.g., the slot machine)                 participate in a promotion to be presented by the mobile                 gaming device. For example, the central server may                 determine whether sound to be broadcast by the device                 would be audible to the player of the mobile gaming                 device given the ambient noise levels in the casino. As                 another example, the central server may determine                 whether or not the device is currently occupied and                 therefore whether the device should be used at all in                 presenting the promotion. In some embodiments, an                 effective direction of a device may be determined for                 one or more devices. The effective direction may include                 a viewing direction (e.g., a direction that a display is                 facing) and a listening direction (e.g., a direction                 that a speaker is facing). Such an effective direction                 may be determined, for example, through analysis of a                 photograph of a device, by a person entering information                 about a device, by a direction sensor of a device, and                 so on. Such information may be used to determine when to                 place a promotion on a device (e.g., so that promotions                 are placed on devices with effective directions that                 face desired targets).             -   In various embodiments, a device (e.g., a slot machine)                 may be the sole presenter of a promotion. The mobile                 gaming device may not be involved in presenting a                 promotion to a player. However, the mobile gaming device                 may signal the device (e.g., the slot machine) to make                 the presentation. For example, a player with a mobile                 gaming device may walk by a slot machine. The mobile                 gaming device may transmit a signal to the slot machine                 to present a promotion. Accordingly, the slot machine                 may present video, audio, or other information                 associated with the promotion. In the mean time, the                 mobile gaming device may continue to allow the player to                 play a game without the mobile gaming device becoming                 involved in the promotion. In various embodiments, two                 or more devices may be involved in presenting a                 promotion to a player. The mobile device may not be                 involved in the presentation. However, the mobile device                 may signal to the devices to present material in                 accordance with the promotion.     -   1.9. Message about where to go to get something. For example,         the mobile device knows where you are and can tell you if you're         near the jewelry store and what you can get there. In various         embodiments, a promotion may include a message indicating where         a product or service may be bought, used, or experienced. For         example, a mobile gaming device may present a text message to a         player indicating that there is a jewelry store to the right of         the player. For example, a mobile gaming device may present an         audio message to a player indicating that there is a show         playing around the corner. In various embodiments, when a player         with a mobile gaming device walks near a retail store or other         locality of interest, a promotion may be triggered. The         promotion may relate to that locality. -   2. Mediums. Places where promotions may be placed. Images or videos     associated with promotions may be presented in various places.     Images and videos associated with promotions may be presented on a     display screen of a mobile gaming device. Images and videos may be     presented on the display screen in different places, and under     different circumstances. For example, an image may be presented in     the foreground or background, during a game or between games. Other     outputs associated with promotions may also be presented in various     ways.     -   2.1. Symbols. In various embodiments, images or video associated         with a promotion may be put on a symbol. In various embodiments,         images or video associated with a promotion may make up the         whole of a symbol. For example, an image of a soda drink may         make up a symbol. Symbols with such images or videos may         function in a game just as any other symbol. For example, in a         slot machine game, the alignment of three like symbols may allow         a player to win a prize. Images or video associated with a         promotion my be put on cards; game tokens (e.g., a game token         that moves around a board in a game of Monopoly® may take the         form of an image of a luxury car brand); game characters (e.g.,         a bidder in an auction game may take the form of an animated         Clorox™ box); tokens of value (e.g., when a player of a game         opens a treasure chest, three sparkling Rolex® watches may be         revealed); and so on.     -   2.2. The background, e.g., background graphics. Images or video         associated with a promotion may appear as background graphics on         the display screen of a mobile gaming device. For example, the         parts of the screen that are not occupied by graphics related to         a game may be occupied by images or video related to a         promotion.     -   2.3. Signs. Images or video associated with a promotion may         appear on signs or other landmarks in a virtual world associated         with a game. For example, a game played on a mobile gaming         device may feature a virtual world with racing cars. The cars         may pass billboards in the virtual world. The billboards may         include images promoting products or services.     -   2.4. Chip faces, such as the faces on gaming chips. In various         embodiments, images or video associated with a promotion may         appear on gaming chips. Such gaming chips may be actual,         physical gaming chips, such as those used in table games at         casinos. Such gaming chips may also include chips used in a game         played on a computing device, such as on a mobile gaming device.         For example, a player may engage in a game of poker using his         mobile gaming device. Gaming chips which are graphically         depicted in the game may include images associated with a         promotion, such as images of products or services.     -   2.5. Cards. In various embodiments, images or video associated         with a promotion may appear on cards. Such gaming cards may be         actual, physical cards, such as those used in table games of         poker or blackjack. Such cards may also include cards used in a         game played on a computing device, such as on a mobile gaming         device. For example, a player may engage in a game of poker         using his mobile gaming device. Cards which are graphically         depicted in the game may include images associated with a         promotion, such as images of products or services.     -   2.6. Audio. In various embodiments, the audio outputs of a         mobile gaming device may be used as part of a promotion. The         audio outputs may broadcast songs, jingles, voice, tunes,         narrative, sounds of products (e.g., the sounds of a horse         stamping in an advertisement for horse-back riding).     -   2.7. Promotions appear in a bonus round. The whole theme of the         bonus round could be based on the promotions. In various         embodiments images or video associated with a promotion may         appear in the bonus round of a game. The bonus round may include         any game sequence that is not part of the normal flow of the         game, and in which a player has the opportunity to win unusual         amounts of credits. For example, in a Wheel of Fortune® game, a         bonus round may include a spin of a simulated wheel in which a         player is given the opportunity to win large prizes posted on         the wheel. Promotional images may be displayed in the background         of a bonus round scene. Promotional images may also function as         characters or game tokens in a bonus round. For example, a         cereal box may be the main character in bonus round, with the         cereal box moving around a game board and landing on squares         which win money for the player. In various embodiments the theme         of a bonus round may center around a particular promotion. For         example, a bonus round set in a chocolate factory may be         designed to promote the Mars company. In various embodiments,         audio associated with a promotion may be broadcast during a         bonus round. For example, the hissing sound of a soft drink         bottle opening may be broadcast whenever the player has won more         money in the bonus round.     -   2.8. Pop-up ads. In various embodiments, pop-up boxes or windows         may be used to display videos or images associated with         promotions. Pop-up boxes or windows may include separate windows         that appear on a display (e.g., on the display screen of the         mobile gaming device) without prompting from a player. Images or         video associated with the promotion may be displayed within the         pop-up boxes or windows.     -   2.9. Housing. In various embodiments, promotions may be placed         on a casing, housing, or other hardware components of a mobile         gaming device. For example, the housing of a mobile gaming         device may be decorated in the coloring of a Coca-Cola can. In         various embodiments, promotions may be put on accessories of a         mobile gaming device, such as on a leather case of an iPod, such         as on the holster of a Blackberry™, such as on a dock of an         iPod, or on any other accessory.     -   2.10. Constraints. Symbols have inherent constraints. For         example, they consist of graphics. Symbols might be only certain         pixel dimensions, such as 20×20 pixels. In various embodiments,         a particular medium or slot for the display of images or video         may have inherent constraints.         -   Accordingly, a marketer who wishes to use such a medium or             slot for the presentation of a promotion may have to devise             images or video which satisfy the constraints presented by             the medium. For example, an image associated with a             promotion may take the place of (or may serve as) a symbol             in a reeled slot game. As the symbol may occupy only a small             portion of the area of the display screen, the image or             video associated with the promotion may likewise be             constrained to occupy only that small area of the display             screen. The symbol may have a stated constraint in terms of             size. For example, the symbol may occupy an area of 0.36             square inches, or an area of 20 by 20 pixels. Any image or             video that is to serve as a symbol must thus be confined to             the stated area limits. In various embodiments an image or             video associated with a promotion is constrained to occupy a             certain area. The area may be measured in terms of square             inches, dimensions, square millimeters, or in terms of any             other units. In various embodiments, the central server or             other party selling promotional opportunities to marketers             may publish or otherwise inform potential marketers of the             constraints placed on various types of promotions. For             example, the central server may list available places to             display images or video and may list corresponding size             constraints. For example, the following may be a partial             list of mediums and constraints: (a) symbol, 20×20             pixels; (b) billboard in bonus round, 30×50 pixels; (c)             background left side of screen, 70×20 pixels; (d) background             top of screen, 20×80 pixels; and so on. In various             embodiments, the cost to a marketer of displaying an image             or video may be based, at least in part, on the display area             of the image or video. For example, the cost to the             advertiser may be proportional to the display area of the             image or video. In various embodiments, the cost to the             marketer for a promotion may depend on other factors as             well, such as the duration for which a promotion is             presented, the point in a game at which a promotion is             presented, the number of times a promotion is presented             (e.g., the cost per presentation may go down if there are             multiple presentations), and so on.         -   In various embodiments, there may be time constraints placed             on a promotion. For example, a promotion must last no more             than 3 seconds. Thus, any video associated with the             promotion may be constrained to lasting no more than 3             seconds. Also, any audio associated with the promotion may             be constrained to lasting no more than 3 seconds. In various             embodiments, the cost to a marketer for having a promotion             presented may depend, at least in part, on the duration of             the promotion.         -   In various embodiments, an image may be constrained to be at             least a certain size, or to occupy at least a certain area.             For example, an image may be constrained to be at least 20             by 20 pixels. In this way, the casino server can ensure that             empty space is kept to a minimum on a display screen.             Similarly a video may be constrained to take up at least a             certain amount of area. In various embodiments, an image or             video may be constrained to be exactly a particular size. In             various embodiments, an audio clip associated with a             promotion may be constrained to be exactly a particular             duration. In this way, the casino server may ensure that             there is no undesired quiet time.     -   2.11. Additional Non-Game Objects. In various embodiments, an         object that is not typically part of a game or gaming interface         may be added to a game or gaming interface as part of a         promotion. For example, representation of a can of Coke or any         other product being advertised may be added to an interface that         displays a card table. The can or other object may simulate the         placement of a can or other subject on a physical table. In some         implementations, the object may be stationary. In other         implementations, the object may move about the interface (e.g.,         the object may include a mascot that moves, dances, etc.). -   3. Player indicates his preferences in advertising. In various     embodiments, a player may influence the promotions that are     presented to him. When the player has an input into which promotions     are presented to him, the player may be more likely to respond     positively to the promotions.     -   3.1. In a game with advertising on various game elements, the         player selects the category, genre, brand or other rubric from         which ads are selected. This information on player ad         preferences may itself be valuable since the player has just         answered a survey question. For example, when the game is about         to start, the opening screen can display three options (e.g.,         three large boxes with descriptive text and graphics) to be         picked using the touch screen. In various embodiments, a player         may indicate a type, category, or other limitation on a         promotion. Promotions may then be presented to the player based         on the indicated type or category. Such a type or category may         represent a preference of the player. For example, the player         may prefer to see vacation related commercials, car related         commercials, or food related commercials. In indicating a         category of promotion, player may indicate: (a) a type of         product; (b) a type of service; (c) a price range for a product         or service; (d) a brand; (e) a manufacturer; (f) a format of the         promotion (e.g., the promotion is a movie trailer; e.g., the         promotion should last only five seconds; e.g., the promotion may         be an infomercial; e.g., the promotion should be video; e.g.,         the promotion should be audio); (g) a particular product (e.g.,         the player may wish to see a promotion about a Mercedes of a         particular model and year); (h) a particular cause (e.g., the         player may wish to see promotions for products or charities that         benefit a particular cause, such as the environment); (i) a         particular attribute of a product (e.g., the player may indicate         that he/she wishes to see only red clothes); (j) a retailer         (e.g., the player may indicate the he/she wishes to see products         from Macy's); (k) whether a promotion will promote a particular         product or service or just be informational; and so on.         -   In various embodiments, a player may indicate a category of             promotion in various ways. When first receiving a mobile             gaming device, a player may indicate a category of             promotion. The player may indicate a category by informing a             casino representative. The casino representative may then             program a setting onto the mobile gaming device such that             the mobile gaming device only presents promotions of the             category indicated by the player. The player may also make             an indication using the mobile gaming device. For example,             the player may select a category of promotion from a menu,             from a series of check boxes, or from a text box. Using a             text box, a player may key in a category of promotion, or             any description of a promotion the player so desires. For             example, the player may key in, “show me things to do in             Kansas during August”. In various embodiments, the player             may go through two or more rounds of specifying a promotion.             For example, the player may first specify a broad category             such as automobiles. The player may then specify a narrower             category, such as “cars” or “trucks”.         -   In various embodiments, a player may indicate category of             promotion via the Internet. For example, prior to a casino             visit, a player may visit the Internet. The player may             navigate a series of menus, checkboxes, text boxes, or other             input mediums in order to specify a category of promotion.             The indicated category of promotions may be stored by the             casino server. The casino server may then ensure that, while             playing, the player is only presented with promotions             falling under the given category. In various embodiments,             the mobile gaming device may filter out promotions so that             only those of a category indicated by a player are presented             to the player. In various embodiments, promotions of a             category related to that selected by the player may be             presented to the player.         -   In various embodiments, a player may indicate a new category             of promotions some time during the course of a playing             session. For example, a player may indicate that she is no             longer interested in see promotions related to jewelry, and             instead would like to see promotions related to purses. A             mobile gaming device may include a menu or icon that is             accessible during a playing session. The player may access             such a menu or icon to indicate a change to the category of             promotion.         -   In various embodiments, a player may first see one or more             promotions. The player may then indicate whether he would             like to see additional, similar promotions, or whether he             would like to see promotions of a different type. Based on             his response, new promotions may be presented to the player.             The player may once again be asked whether he would like to             see similar promotions or promotions of a different type. In             this way, the casino server may iteratively arrive at a             category of promotion that is of interest to the player.         -   In various embodiments, a player may indicate a category of             promotion. The promotions presented to the player may or may             not then all conform to the indicated category. For example,             the casino server may not necessarily have an inventory of             promotions to present to the player of the category             indicated by the player. In various embodiments, the casino             server may determine promotions that are deemed to most             closely fall within the category indicated by a player, even             if such promotions do not directly fall within the category             indicated by the player. For example, the player may             indicate a desire to see promotions related to vacationing             in the Bahamas. The casino may not have any promotions             directly on topic. However, the casino may have promotions             related to vacationing in the Virgin Islands. Thus, the             casino may present such promotions to the player. The casino             may employ algorithms for associating related concepts. The             algorithms may learn from the preferences indicated by             players. For example, if a given player indicates that he             wishes to be presented with promotions related to concept A             and concept B, then the algorithms may associate concept A             with concept B. In the future, if another player indicates             he wished to be presented with promotions related to concept             A, the casino server may present to the player promotions             related to concept B. As will be appreciated, many             algorithms could be used for deriving associations between             concepts. Any such algorithm might be used for choosing             promotions to present to a player, in various embodiments.         -   In various embodiments, a player may indicate a category of             promotion. By indicating such a category, the player may             reveal himself to be a potential customer of a merchant who             would create a promotion falling within the indicated             category. For example, a player may indicate that he wishes             to view promotions for luxury cars. By providing such an             indication, the player may reveal himself to be a potential             buyer of luxury cars. The knowledge that the player is a             potential buyer of luxury cars may be of value to a dealer             or manufacturer of luxury cars. Thus, in various             embodiments, if a merchant deals in a category of goods or             services and a player has indicated a preference to view             promotions related to that category, then the casino may             provide the merchant with the player's contact information.             The merchant may then be able to send further promotions to             the player. For example, the merchant may be able to send             promotions to the home of the player. In some embodiments, a             merchant may pay the casino to provide the contact             information of a player who has indicated interest in seeing             promotions in a category in which the merchant's products             fall.         -   In some embodiments, a merchant not be given direct contact             information for a player who has shown interest in             promotions falling within the merchant's area of business.             Rather, the casino may forward promotions from the merchant             to the player, even after the player has left the confines             of the casino. For example, the merchant may send a             promotional email to the casino, and the casino may forward             the promotional email to the player. In this way, the             player's contact information may be kept from the merchant,             and the player's privacy may be maintained.         -   In various embodiments, a player may indicate a particular             category of promotion. The casino may then find marketers             who might be expected to run promotions falling under that             category. For example, a player may indicate he wishes to             see promotions related to car insurance. The casino may then             find various car insurance companies. The casino may invite             the marketers to promote to the player. In various             embodiments, the casino may provide a general description of             the player to a marketer. For example, the casino may             provide the marketer with an age, income level, and/or other             demographic characteristic of the player. The information             about the player that is provided to the marketer may aid             the marketer in deciding whether or not to promote to the             player. Based on information about the player, marketers may             determine whether or not they wish to promote to the player.             For example, a marketer may decide based on the age of a             player whether or not the player would be likely to purchase             the marketer's product. The marketer may make a decision as             to whether or not to promote to a player simply based on the             fact that the player has shown interest in a particular             category of promotion. In various embodiments, the casino             may quote a price to the marketer to promote to a particular             player. The marketer may accept or reject the offer to             promote.         -   In various embodiments, the casino may quote a range of             prices, each price corresponding to different limitations on             the promotions. For example, a first price may be quoted for             placing a symbol on a reel, a second price may be quoted for             filling the whole screen with a 30-second video, and so on.         -   In various embodiments, the casino may solicit bids from             marketers to present promotions to a particular player. The             marketers that place the highest bids for a given medium or             slot may be given the opportunity to present a promotion to             the player. In various embodiments, more than one marketer             who bids may be given the opportunity to promote to a             player. The marketers with the higher bids may be given             preferential slots. For example, the marketer with the             highest bid may be given the largest screen area in which to             promote. For example, the marketer with the highest bid may             be given the longest time slot in which to have a promotion             presented.         -   In various embodiments, the casino server may contain an             inventory of promotions that are available to present to a             player. The casino server may store rules (e.g., rules             provided by the sponsor of the promotion) which describe the             criteria for presenting the promotions. A promotion may be             stored as one or more computer files, including image files,             audio files, video files, and so on. In various embodiments,             the casino may request promotions from marketers. For             example, upon receiving an indication of a category of             promotion from a player, the casino may solicit promotions             from marketers who might wish to present promotions falling             within the indicated category.     -   3.2. Sponsors or marketers may inform a player as to what         sponsored outcomes he can get. “Pick Pepsi and get free spins”.         In various embodiments, a player may be informed of a benefit he         can receive in exchange for agreeing to view a promotion. In         various embodiments, a player may be informed of a benefit he         can receive in exchange for agreeing to view a category of         promotion. In various embodiments, a marketer may be willing to         compensate a player for viewing or listening to a promotion. The         compensation may take a number of forms. Compensation may         include: (a) money; (b) gaming chips or gaming credits; (c)         increased odds of winning; (d) higher payouts (e.g., a jackpot         may be increased); (e) reduced costs of wagering (e.g., a player         may be given the opportunity to make a wager for 5 that would         normally have been 10); (f) a free game (e.g., a free spin at a         slot machine; e.g., a free game of video poker); (g) a free         opportunity to enter the bonus round; (h) hints given in a game         (e.g., in a game of video poker, a player may receive         hints); (i) a free or discounted music download; (j) a free or         discounted software download; (k) a free or discounted ring-tone         download; (l) a download of a video, cartoon, movie trailer,         animation, television pilot episode, news clip, or other         sequence; (l) a cashless gaming ticket; (m) a ticket to a         show; (n) a ticket to a movie; (o) complementary (comp)         points; (p) a voucher; (q) a gift certificate; (r) a voucher for         a free meal; (s) a free or discounted stay in a hotel room; and         any other benefits. A marketer may provide any benefit either         directly or indirectly to a player. In various embodiments, a         marketer may directly provide cash to a player in exchange for         the player agreeing to view a promotion of the marketer. In         various embodiments, a marketer may provide compensation to the         casino, and the casino may in turn provide a benefit to the         player, such as increased odds of winning. The compensation         provided to the casino may be equal to the expected cost to the         casino of providing the benefit to the player.         -   In various embodiments, two or more marketers may contribute             to a benefit which will be provided to a player. For             example, each of two automobile manufacturers may contribute             a portion of the benefit that will be provided to a player             for viewing automobile related promotions.         -   In various embodiments, a player may receive a fixed benefit             from the casino for agreeing to be presented with             promotions. The casino may then sell to marketers             opportunities to present promotions to the player. The             casino may attempt to sell such opportunities for as much             money as it can get. The casino may profit from the             difference in value between the benefit provided to the             player and the amounts received from the marketers.         -   In various embodiments, a player may be presented with a             table or other listing of benefits he might receive,             together with criteria for receiving the benefits. For             example, a table may include a first column listing             different categories of promotion. A second column in the             table may list benefits the player would receive in exchange             for being presented with such promotions. For example, a             line in the table might list, “Watch Pepsi Ads” as the             category of promotions, and “Get 10 Free Spins” as the             benefit. -   4. Triggers for promotions. Promotions may be presented at various     times and under various circumstances. In one situation, a player     may be engaged in playing a game on the mobile gaming device. A     promotion may be presented to the player on the screen while the     game is occurring (e.g., the promotion is presented as a symbol;     e.g., the promotion is presented on screen space to the side of the     screen space displaying the game), on the screen between games, on     the screen while a resolution of a game is pending, as an audio     broadcast during the game, and so on. In one situation, a player may     not be engaged in playing a game and promotions may be presented to     on the mobile gaming device. Promotions may be presented     continuously, periodically, sporadically, when the mobile gaming     device comes to a particular location, and so on.     -   4.1. Broadcasting of advertising content to others physically         near a player. If a player is near others, the volume on your         device can go up so that others hear the advertising on your         device. “You have just won a FREE COKE”. In various embodiments,         a promotion may be triggered by the presence of a nearby human         being. The nearby human being may be someone other than the         player of the mobile gaming device which is presenting the         promotion. For example, if the mobile gaming device detects the         presence of a human being other than the player, the mobile         gaming device may broadcast a promotion. In various embodiments,         the mobile gaming device may broadcast a promotion in response         to the presence of any human being, including the player of the         mobile gaming device. A mobile gaming device may detect the         presence of another human being in various ways. The mobile         gaming device may include a microphone. The microphone may pick         up ambient audio signals. The mobile gaming device may analyze         ambient audio signals for tell-tell human sounds, such as the         sound of a voice, the sound of breathing, the sound of steps,         and so on. For example, the mobile gaming device may use special         software which is tuned to recognize voice signals. The mobile         gaming device may recognize the presence of humans by other         means. For example, the mobile gaming device may include a heat         or infrared sensor. The mobile gaming device may use such a         sensor to pick up the heat signatures of humans. In various         embodiments, the mobile gaming device may include a camera. The         camera may periodically snap pictures of its surroundings. The         mobile gaming device may include image processing software for         analyzing the pictures. The image processing software may have         the capability to recognize images associated with humans. In         various embodiments, the mobile gaming device may recognize the         presence of humans via devices associated with the humans. For         example, the mobile gaming device may recognize the signal from         a nearby cell phone, e.g., by receiving the signal at an antenna         associated with the mobile gaming device. Presumably, the cell         phone is being carried by a human. Thus, by recognizing the         presence of a cell phone, the mobile gaming device may be         indirectly recognizing the presence of a human. In various         embodiments, the mobile gaming device may recognize the presence         of another mobile gaming device. Presumably, the other mobile         gaming device is being held or carried by another human. Thus,         by recognizing another mobile gaming device, the first mobile         gaming device may indirectly recognize the presence of another         human.         -   In various embodiments, upon recognizing the presence of             another human, the mobile gaming device may present a             promotion. The promotion may thereby have the chance of             being perceived not only by the player of the mobile gaming             device, but also by the other human who is in proximity to             the mobile gaming device. The effect of the promotion may             thereby be amplified.         -   In various embodiments, upon recognizing the presence of             another human, the mobile gaming device may increase the             volume with which a promotion is presented. The increased             volume may make it more likely that the other human will             perceive the promotion.         -   In various embodiments, upon recognizing the presence of             another human, the mobile gaming device may increase the             brightness of a display. Increasing the brightness of its             display may make it more likely that the other human may             perceive the graphics on the display. Such graphics may             include graphics associated with promotions.     -   4.2. Broadcasting with more light in a brightly-lit environment         (e.g., in the pool). In various embodiments, a mobile gaming         device may increase the brightness of its display based on the         strength of ambient light. For example, the mobile gaming device         may increase the brightness of its display as the brightness of         ambient light increases. For example, the mobile gaming device         may make its display bright if the mobile gaming device is         outside in the sunlight, while the mobile gaming device may make         its display dimmer when the mobile gaming device is within a         casino. In various embodiments, a mobile gaming device may         include a light sensor. The sensor may detect ambient light         conditions. Based on readings from the sensor, the mobile gaming         device may either increase or decrease the brightness of its         display. In various embodiments, increasing the brightness of a         display may make it easier for a player of the mobile gaming         device to perceive promotions and/or other graphics while in the         presence of bright light. In various embodiments, decreasing the         brightness of its display may allow the mobile gaming device to         increase battery life. Thus, in various embodiments, the mobile         gaming device may decrease the brightness of its display in         areas where a bright display is not needed, such as indoors.     -   4.3. Somebody near you wins. For example, someone on slot         machine nearby wins. Your mobile device says, “You can have that         too, if you'll just . . . ” In various embodiments, a promotion         may be presented to a first player of a mobile gaming device         based on the game results of a nearby player. The nearby player         may be a player of a slot machine, video poker machine, mobile         gaming device, or any other gaming device. The nearby player may         have just: (a) won a game; (b) won a large payout (e.g., a         payout of 40 or more coins); (c) won a jackpot; (d) entered into         a bonus round; (e) had a near miss; (f) lost a game; (g) run out         of money; (h) cashed out; or may have been involved in any other         game event or outcome. Based on the game event, result, or         outcome of the nearby player, promotion may be presented to the         first player.         -   In various embodiments, if the nearby player has had a             favorable outcome, then a promotion may be presented to the             first player. The promotion may offer the first player the             opportunity to experience a similar outcome as has the             nearby player, if the first player will only engage in some             activity. The activity may include viewing ad advertisement             or presentation, test driving an automobile, answering a             survey question, testing or sampling a product or service,             providing some information about him or herself (e.g.,             demographic information), providing contact information             about himself, providing contact information about another             person (e.g., a friend; e.g., a family member), and so on.             Thus, for example, the first player may have the opportunity             to experience an outcome similar to the outcome that the             nearby player has just experienced if the first player would             only view a ten-minute promotion on his mobile gaming device             and answer two survey questions related to the promotion.         -   In various embodiments, a mobile gaming device may determine             the results or outcomes of a nearby player in various ways.             The mobile gaming device may transmit to the casino server             its location. The casino server may determine a gaming             device that is proximate to the location of the mobile             gaming device. The casino server may determine an outcome             that has just occurred at the gaming device. The casino             server may transmit to the mobile gaming device an             indication of the outcome.         -   If the first player accepts the offer of his mobile gaming             device, then the mobile gaming device may allow the first             player to engage in the activity. For example, the mobile             gaming device may present a ten-minute promotion and then             present survey questions about the promotion for the first             player to answer. Once the first player has successfully             engaged in the activity, the mobile gaming device may             provide the first player with the same outcome as had been             achieved by the nearby player. For example, if the nearby             player had won a payout of 50 credits, the first player may             be given 50 credits. For example, if the nearby player had             won entry into a bonus round, then the first player may be             given entry into the bonus round.     -   4.4. You win an outcome. In various embodiments, a promotion may         be presented to a player if the player has achieved a winning         outcome. A promotion may be presented to a player if the player         has: (a) received a positive payout; (b) received a payout that         is greater than the amount wagered; (c) received a payout that         exceeds a certain threshold (e.g., 10 coins); (d) achieved entry         into a bonus round; and so on. The time when a player achieves a         winning outcome may be an opportune time to present a promotion         to the player, because the player may be in a good mood. The         player may thereby be more receptive to the message of the         promotion. The player may also transfer the positive feelings         associated with the winning outcome to the subject of the         promotion. For example, if a particular brand of potato chips is         presented to a player right after the player has achieved a         winning outcome, then the player may associate those potato         chips with the positive feeling of winnings.         -   In various embodiments, a marketer may pay more to have its             promotion presented if the promotion is presented following             a winning outcome. This may occur because the player may be             more likely to have positive feelings associated with the             promotion following a winning outcome than following a             non-winning outcome. Thus, in various embodiments, a             marketer may pay a first amount to have a presentation             promoted at a first time not following a winning outcome,             and may pay a second amount which is greater than the first             amount to have the promotion presented at a second time             following a winning outcome.     -   4.5. You win a big payout. In various embodiments, a promotion         may be presented to a player if the player has won a large         payout. A large payout may be defined as a payout exceeding X         credits, where X may be e.g., 50, 100, 1000, or any threshold         number of credits. In various embodiments, a large payout may be         defined as a payout whose quantity is greater than X multiple of         the amount wagered, where the multiple may be e.g., 50, 100,         1000, or any threshold multiple.     -   4.6. You win a certain amount. In various embodiments, a         promotion may be presented to a player if the player has won a         certain aggregate amount. The aggregate amount may represent         total payouts over a certain period less amounts wagered. The         aggregate amount may represent total payouts regardless of         amounts wagered. For example, a promotion may be presented to a         player if the player has won 100 coins net of amounts wagered         over the past hour.     -   4.7. You have a near miss. In various embodiments, a promotion         may be presented to a player if the player has had a near miss.         For example, if the player has achieved four cards to a royal         flush, if a person has achieved four out of five required         jackpot symbols, or if a person has landed one spot away on a         spinning wheel from the jackpot space, the player may be         presented with a promotion. The promotion may read, “Oh, so         close—well, at least you can rent a car for only 20 per day at         Jim's car rental.” In some embodiments, a promotion may offer         the player the chance to achieve the missed outcome if the         player will perform some activity. For example, if the player         agrees to spend a day in a cabin in a retirement community, the         player may receive a payout as if he had achieved the nearly         missed outcome.     -   Location. In various embodiments, a promotion may be triggered         by the location of a player. In various embodiments, a promotion         may be presented to a player if the player is in a first         location, but not if the player is in a second location. In         various embodiments, a first promotion may be presented to a         player if the player is in a first location, and a second         promotion may be presented to the player if the player is in a         second location. In various embodiments, a promotion may be         presented to a player if the mobile gaming device of the player         is in a particular location. The player may be assumed to be in         the same location as the player.         -   4.7.1. Walk by a store. In various embodiments, a promotion             may be triggered as a mobile gaming device comes into the             proximity of a store. The promotion may show images or video             depicting products in the store. The promotion may present             text descriptions of store items. The promotion may describe             available discounts within the store. In various             embodiments, a promotion may be triggered as a mobile gaming             device comes into proximity of any retailer, such as a             store, a restaurant, a roadside stand, a gas station, a car             repair shop, and so on. Proximity may be defined, in various             embodiments, as being within 100 feet, as being on the same             block, as being within sight, as being within walking             distance, as being within a mile, as being directly in front             of, or as any other appropriate distance range.             -   In various embodiments, a promotion may include an offer                 of a benefit if the player of the mobile gaming device                 walks into the retailer, buys a product at the retailer,                 tests a product at the retailer, or otherwise interacts                 with the retailer. The benefit offered may include: (a)                 money; (b) gaming chips or gaming credits; (c) increased                 odds of winning; (d) higher payouts (e.g., a jackpot may                 be increased); (e) reduced costs of wagering (e.g., a                 player may be given the opportunity to make a wager for                 5 that would normally have been 10); (f) a free game                 (e.g., a free spin at a slot machine; e.g., a free game                 of video poker); (g) a free opportunity to enter the                 bonus round; (h) hints given in a game (e.g., in a game                 of video poker, a player may receive hints); and so on.                 Thus, for example, a player of a mobile gaming device                 may receive an offer of 10 free spins in a game of slots                 if he walks into a retailer.             -   In various embodiments, a representative of a retailer,                 such as a store owner or manager, may be informed as a                 mobile gaming device approaches the store. The                 representative of the retailer may have the opportunity                 to decide on an offer for the player in substantially                 real time. For example, the representative may determine                 whether any items in the store are currently                 overstocked. The representative may accordingly offer                 the player a special discount on such items. The                 representative may also be given information about the                 player. For example, the representative may receive                 information about the player's age, race, marital                 status, gender, and so on. The representative may also                 receive information about recent outcomes achieved by                 the player. The representative may use such information                 in tailoring a promotion for the player. For example, if                 the player is a man, the store owner may offer him a                 discount on a tie. If the player is a woman, the store                 owner may offer her a discount on a blouse. The mobile                 gaming device may transmit information about the player                 to nearby stores, thus allowing store representatives to                 learn information about the player. In various                 embodiments, the mobile gaming device may transmit to a                 nearby retailer a player identifier, such as a player                 name. The retailer may transmit to the casino server the                 player identifier. The retailer may thereupon receive                 from the casino server further information about the                 player. Information received about a player may                 include: (a) the last outcome achieved by the                 player; (b) the last large outcome received by the                 player; (c) total winnings for the player in the past X                 period of time (e.g., total winnings for the player in                 the last 10 minutes, the last day, the last hour, the                 last two days, etc.); (d) net or gross winnings for a                 player in the last X period of time; and so on.             -   In various embodiments, a retailer may include a retail                 computer or retail server. The computer or server may                 execute algorithms for determining a promotion for a                 passing player. The promotion may be determined based on                 conditions within the store. The promotion may also be                 determined based on information received about the                 player. For example, the promotion may be determined                 based on whether the player has recently won a                 significant amount of money while gambling. For example,                 if a player has won a large amount of money recently,                 the store may promote to the player a relatively                 expensive product. The idea behind the promotion may be                 that the player is in a good spending mood in light of                 his recent good fortune. The retail server may receive                 signals from the mobile gaming device and/or from the                 casino server, with such signals describing information                 about the player. The retail server may use such                 information to automatically determine a promotion for                 the player. The promotion may be automatically                 transmitted to the mobile gaming device of the player.                 The promotion may then appear on the screen of the                 mobile gaming device. The promotion may be broadcast                 using speakers of the mobile gaming device. In various                 embodiments, the retail server may determine a promotion                 for the player. The retail server may display an                 indication of the promotion to a representative of the                 retailer. The representative may then communicate the                 promotion to the player. For example, the representative                 may walk out in front of the retail establishment, greet                 the player, and present the promotion to the player                 (e.g., offer the player a discount on a product within                 the store).             -   In various embodiments, a retailer and/or the casino                 server may track purchase data from players. For                 example, the retailer and/or the casino server may                 maintain a database. The database may include                 information about a player coupled with data describing                 an amount a player spent (e.g., on products or                 services), a type of product purchased by the player                 (e.g., clothes; e.g., shoes; e.g., jewelry); whether or                 not a player tested a product or service, whether or not                 a player walked into a store, whether or not a player                 indicated interest in an item, and so on. Data about a                 player may include data describing player demographics,                 including age, race, gender, income, marital status, and                 so on. Data about the player may also include data about                 gambling results of the player, possibly including                 recent outcomes achieved, recent amounts won, amounts                 won in the last X period of time, total payouts less                 total amounts wagered in the last X period of time,                 amounts wagered, amounts wagered per game, and so on.                 The database may thus include demographic information                 about a player, information about the gambling results                 of the player, and purchasing results of the player. The                 database may contain such information about a large                 number of players. For example, the database may contain                 one record for each player. Each record may include                 information about a player's demographics, purchasing                 information, and information about gambling results                 achieved.             -   In various embodiments, an algorithm may be used to                 derive correlations between two types of information                 such as purchasing decisions and gaming outcomes                 achieved prior to the purchasing decision. For example,                 algorithms may be used to determine correlations between                 amounts won while gaming during a given period of time,                 and amounts spent at a retailer following the period of                 time. The output of the algorithm might indicate, for                 example, that the more a player wins during the hour                 prior to visiting a retail store, the more the player is                 likely to spend at the retail store. The output may                 indicate that after play of a certain type of game for a                 certain period of time, a player of a certain age and                 gender is likely to be effected by a certain type of                 promotions.             -   In general, given historical information about players'                 gaming outcomes and purchasing decisions, and given                 information about a particular player's recent gaming                 performance (or gaming performance over more than just                 the recent past), algorithms may be used to predict the                 particular player's likely purchasing decisions. Such                 algorithms may be used to predict a player's likely                 response to promotions. For example, a representative of                 a retail establishment may receive information about an                 approaching player. The information may indicate that                 the player has won a jackpot in the last hour. The                 retailer may key that information into a predictive                 algorithm. The algorithm may tell the retailer that the                 player is more likely than a typical person to want to                 purchase an expensive item. The algorithm may further                 recommend an item to offer to the player. The algorithm                 may have access to a database or other listing of store                 items. The algorithm may have access to a database or                 other listing of prices, costs, or other measures of                 value of store items. Based on predictions of the                 player's spending, and based on the descriptions of                 items and their values, the algorithm may determine                 which item to offer to the player. The algorithm may                 output a test description of such item to the store                 representative. The representative may approach the                 player and inform the player that this item is available                 and even that the player may receive a special discount                 on the item.             -   In some embodiments, the algorithm may transmit a                 promotion directly to the mobile gaming device of the                 approaching player. For example, the algorithm may                 transmit a promotion indicating that a fine coat is                 available only to that player for $700.             -   In various embodiments, data recorded about a player may                 include data describing promotions presented to the                 player. Data recorded and/or stored may further include                 data describing a player's reaction to the promotions                 presented to him. Algorithms may be used to correlate                 information about the players' recent gaming outcomes to                 players' reactions to promotions. For example, an                 algorithm may find that a player is more likely to                 respond to humor-based promotions when the player has                 just won money, and that a player is more likely to                 respond to value-based promotions when the player has                 just lost money. Thus, algorithms may be used to predict                 which promotion or type of promotion would be most                 effective given a player's recent gaming outcomes.             -   In various embodiments, information about a player's                 gaming outcomes may be received at a retail computer                 from the player's mobile gaming device. In various                 embodiments, information about a player's gaming                 outcomes may be received at a retail computer from the                 casino server. In various embodiments, algorithms used                 to predict which products a player might like to                 purchase may be executed by the casino server. In                 various embodiments, algorithms used to predict which                 products a player might like to purchase may be executed                 by a retail server. Such algorithms may, in various                 embodiments, be executed by the player's mobile gaming                 device. In various embodiments, one or more human                 representatives may work in conjunction with predictive                 algorithms in order to determine a particular promotion                 for a player. For example, a predictive algorithm may                 determine a price range of a product that should be                 offered to a player. Based on that price range, a                 representative may determine a particular product to                 offer to the player, given the representative's                 knowledge of different product pricing. As another                 example, a predictive algorithm may determine a type of                 promotion (e.g., video; e.g., audio; e.g., still image;                 e.g., 30-second; e.g., 5-second; e.g., offer of a                 discount; etc.). A human, such as a representative of a                 retailer, may determine the exact promotion to send to                 the player. In various embodiments, a human may make a                 live presentation of a promotion. For example, a                 representative of a retailer may call a player on his                 mobile gaming device. The mobile gaming device may, for                 example, function as a cellular telephone. The human may                 make a sales pitch to the player. A human may also                 present a promotion via text. In various embodiments,                 the determination and presentation of a promotion may be                 done automatically, without any human intervention. For                 example, a player with a mobile gaming device may                 approach a retail store while walking in the hallways of                 a mall. The mobile gaming device may detect its own                 coordinates using an internal positioning system. The                 mobile gaming device may transmit its coordinates to a                 casino server. The casino server, based on the                 coordinates, may determine that the mobile gaming device                 is near to a particular retail store. The casino server                 may have previously received information about gaming                 outcomes of the player via signal from the mobile gaming                 device. The casino server may thereupon use information                 about the player's recent gaming outcomes, together with                 information about the products at the retail store, to                 derive a promotion for the player. The casino server may                 transmit such a promotion to the player. In some                 embodiments, the casino server may transmit the                 promotion to the retail store. The retail store may then                 relay the promotion to the mobile gaming device of the                 player. As will be appreciated, information about a                 player, such as information about outcomes achieved by                 the player, may be received at various locations, such                 as at a retail store or at a casino server. Similarly,                 as will be appreciated, a promotion can be determined at                 several places, including at a casino server, mobile                 gaming device, or at a retail store. The promotion may                 be transmitted to the mobile gaming device of the player                 from several places, such as from the retail store or                 from the casino server. In various embodiments, the                 mobile gaming device may store information internally                 about a retail store. For example, the mobile gaming                 device may store possible promotions that might be                 available from a retail store. The mobile gaming device,                 based on gaming results of the player of the mobile                 gaming device, may determine which of the internally                 stored promotions to actually present to a player. The                 mobile gaming device may employ predictive algorithms in                 making the presentation.             -   In various embodiments, information about purchasing                 habits of players may be shared among retail                 establishments. For example, a large database may be                 assembled from data gathered at several retail                 establishments. The database may include records for                 various players, some of whom have made purchases at a                 first retail establishment, and some of whom have made                 purchases at a second retail establishment. The larger                 sample size of such a database, as opposed to a database                 with customers of just a single retail establishment,                 may make it possible to come up with better predictive                 algorithms for a player's purchasing decisions.             -   Perspectives for the determination of offers for retail                 establishments In various embodiments, a casino server                 may determine one or more outcomes for a player of a                 mobile gaming device. The casino server may transmit                 such outcomes to the mobile gaming device. The mobile                 gaming device may present such outcomes to the player.                 The casino server may track the location of the mobile                 gaming device. The casino server may determine when the                 mobile gaming device is proximate to a retail                 establishment.             -   The casino server may receive data from the retail                 establishment. For example, the POS terminal of the                 retail establishment may indicate inventory levels of                 various products, and communicate the inventory levels                 to the casino server. The retail establishment may                 communicate other data, such as data about product                 values, product wholesale costs, expected delivery dates                 of new products, historical demand for products,                 customer traffic at the retail shop, and any other                 pertinent data.             -   The casino server may use the data received from the                 retailer to determine promotions on behalf of the retail                 establishment. For example, if the retailer has an                 excess of a certain product, the casino server may                 determine a promotion which offers the product at a                 discount.             -   Based on an outcome generated for a player of a mobile                 gaming device, the casino server may determine a                 promotion for the player of the mobile gaming device.                 The casino server may determine a first promotion if a                 first outcome is generated, and a second promotion if a                 second outcome is generated. For example, if the outcome                 generated is a winning outcome, the casino server may                 determine a promotion which advertises an expensive                 product. If the outcome generated is a losing outcome,                 the casino server may determine a promotion that offers                 a discount to the player.             -   The casino server may determine a promotion to present                 to a player of a mobile gaming device based on the fact                 that a player is within a certain distance of the retail                 establishment, or based on the fact that the player is                 within a certain geographic region, area, or locality.                 For example, the casino server may transmit a promotion                 to the mobile gaming device of a player for presentation                 only if the player is within 50 feet of the retail                 establishment that is being promoted.             -   Thus, a casino server may determine an outcome which has                 been generated for a player of a mobile gaming device.                 The casino server may receive data from a retail                 establishment. The casino server may determine a                 distance between the mobile gaming device and the retail                 establishment. Based on these factors, the casino server                 may determine a promotion which promotes the retail                 establishment to the player. The casinos server may                 cause the promotion to be presented to the player via                 the mobile gaming device of the player. For example, the                 casino server may transmit data to the mobile gaming                 device, where such data describes or encodes the                 promotion. The mobile gaming device may then present the                 promotion to the player. In various embodiments, a                 retail establishment may receive an indication that a                 mobile gaming device is in proximity to the retail                 establishment. The indication may be received via direct                 communication from the mobile gaming device, or via                 communication from the casino server (e.g., the casino                 server may determine that the mobile gaming device is in                 proximity to the retail establishment and may                 communicate such information to the retail                 establishment). The retail establishment may determine a                 promotion for the player of the mobile gaming device.                 The retail establishment may determine such promotion                 based on various data, such as inventory levels, future                 delivery dates for new products, wholesale costs,                 ability to return unsold items, and so on. The retail                 establishment may also receive an indication of an                 outcome achieved by the player of the mobile gaming                 device. The retail establishment may receive any                 information about a player's results, including an                 indication of recent winnings, an indication of a gross                 amount won, an indication of a net amount won, and so                 on. The retail establishment may determine a promotion                 for presentation to the player based on an outcome                 received by the player. The retail establishment may                 determine a promotion for presentation to the player                 based on any historical results of the player. The                 retail establishment may determine a promotion based                 both on the historical results of the player and based                 on the fact that the player is proximate to the                 retailer. For example, if the player is proximate to the                 retail establishment and the player has just won a large                 payout, then the retail establishment may determine a                 promotion which highlights a luxury product of the                 retail establishment. The retail establishment may                 transmit the promotion to the mobile gaming device. The                 retail establishment may transmit the promotion to the                 casino server. The casino server may then transmit the                 promotion to the mobile gaming device.             -   In various embodiments, the mobile gaming device may                 receive information from a retail establishment. The                 information may include information about inventory                 levels, current customer traffic levels, historical                 customer traffic levels, or any other pertinent                 information. The mobile gaming device may determine                 whether or not it is near to the retail establishment.                 If the mobile gaming device is near to the retail                 establishment, then the mobile gaming device may                 determine a promotion to present to the player, the                 promotion serving to promote products or services of the                 retail establishment. The promotion may be determined                 based on information provided by the retail                 establishment. The information provided by the retail                 establishment may be transmitted directly from the                 retail establishment to the mobile gaming device. The                 information provided by the retail establishment may be                 transmitted first to the casino server and then to the                 mobile gaming device. In various embodiments, the retail                 establishment may determine whether or not the mobile                 gaming device is near to the retail establishment. The                 retail establishment may then inform the mobile gaming                 device, either directly or through the casino server. In                 various embodiments, the casino server may determine                 whether the mobile gaming device is near to the retail                 establishment. The casino server may inform the mobile                 gaming device if it is near the retail establishment.             -   4.7.1.1. Use the mobile gaming device as an automatic,                 custom tailored coupon. An individualized coupon. In                 various embodiments, a mobile gaming device may store                 coupons, gift certificates, or other tokens which confer                 value or discounts. Coupons may be transmitted to a                 mobile gaming device at various times. In various                 embodiments, a player may win coupons, gift                 certificates, or other benefits while playing a game.                 For example, if a player lines up three “Macy's” symbols                 on a slot machine, the player may win a 100 gift                 certificate to Macy's.                 -   In various embodiments, the coupons, gift                     certificates, or other tokens of value may be stored                     in electronic form on a mobile gaming device. In                     order to use the coupons, gift certificates, etc.,                     at a retail establishment, the player may bring his                     mobile gaming device to a retail establishment. The                     mobile gaming device may communicate information                     about the coupon, gift certificate, or other token                     to a computer of the retail establishment. The                     communication may occur in various ways. For                     example, the mobile gaming device may communicate to                     the computer of the retail establishment a sequence                     of bits that uniquely identifies a particular                     certificate, coupon, etc. In various embodiments, a                     mobile gaming device may display on its display                     screen a bar code which identifies a coupon, gift                     certificate or other token of value. The bar code                     displayed on the display screen of the mobile gaming                     device may be scanned by the retail establishment,                     e.g., using a typical bar code scanner. In this way,                     the player may carry around coupons, or gift                     certificates on his mobile gaming device. The player                     may redeem them at retail establishments from his                     mobile gaming device.     -   Proximity to another mobile device. In various embodiments,         proximity to a second mobile gaming device may trigger the         presentation of a promotion in a first mobile gaming device.         When the second mobile gaming device is near, the promotion at         the first mobile gaming device may be seen or heard by the         player of the second mobile gaming device.         -   4.7.2. Referral tracking through mobile devices, mobile             device tag. In various embodiments, a player may share a             promotion with one or more other players by specifically             targeting their mobile devices for a promotion (e.g.,             through a targeting interface, by moving close to the other             players, by lining up the mobile devices, etc.). In some             embodiments, the targeted players may agree to receive the             promotion or reject the promotion. In some embodiments, a             player may received increased rewards by targeting more             players with a promotion. To receive the rewards, the             targeted players may have to accept the promotion, act on             the promotion, further target the promotion for transmission             to another player, and/or take any other action. A player             may decrease rewards for targeting players that reject a             promotion so that the player does not randomly target all             players, but rather puts effort into discussing the             promotion with players. In some embodiments, a player may             tag other players' devices with a promotion (e.g., by             touching the device with his or her device, by pressing a             target button, and so on). A tagged device may display a             promotion for some length of time, until a tag is removed             (e.g., by the tagger, by the player of the mobile device,             etc.), etc. In some embodiments, a special promotion or             other reward may become active if a player tags a threshold             number of other devices. In some embodiments, a tagged             player or targeted player may tag or target further players.             The     -   4.8. Time. In various embodiments, time may serve as a trigger         for a promotion. For example, a promotion may be triggered at a         certain time of day, at a certain date, or at a certain year. As         another example, a time since an event may serve as a trigger.         For example, a promotion may be triggered 5 minutes after the         last promotion has been presented.         -   4.8.1. A certain amount of time has elapsed since the last             promotion. In various embodiments, a promotion may be             triggered once a certain amount of time has elapsed from a             prior promotion. The prior promotion may be any promotion.             For example, a current promotion may be triggered to be             presented once one minute has elapsed since the last             promotion on a mobile gaming device was presented. The prior             promotion may be a promotion of the same type or category.             For example, a promotion for toothpaste might be triggered             when it has been 30 minutes since the last promotion for             toothpaste. The same promotion may be triggered, however,             when only 1 minute has lapsed since the last unrelated             promotion. By creating a greater time spacing between             promotions of the same type, player boredom may be             alleviated. In various embodiments, when a certain minimum             time gap is kept between the presentation of any promotion,             player annoyance may be alleviated. In various embodiments,             when a certain maximum time gap is allowed between the             presentation of promotions, player exposure to promotions             may be increased and thus revenues for the casino and for             the marketers may be increased.         -   4.8.2. It is a certain time of day. For example, advertise             food during lunch time. In various embodiments, the             presentation of a promotion may be triggered by the time of             day. Products which are typically purchased during a             particular time of day may be promoted during that time of             day. A promotion for breakfast may be triggered early in the             day, such as at 7:00 am. A promotion for lunch may be             triggered at 11:45 am. A promotion for an evening show may             be triggered at 6:00 pm. A promotion may be triggered based             on a merchant's business hours. For example, a promotion for             a merchant's products may be triggered for presentation at             the time the merchant opens for business.         -   4.8.3. Ambient conditions (e.g., temperature). In various             embodiments, a promotion may be triggered based on ambient             conditions. A promotion may be triggered based on the air             temperature. If the air temperature is over 90 degrees             Fahrenheit, for example, a promotion for a soft drink may be             triggered. A mobile gaming device may contain a temperature             sensor. Readings from the temperature sensor may be used to             trigger promotions. In various embodiments, a mobile gaming             device may contain other sensors for sensing or determining             ambient conditions. A mobile gaming device may contain             humidity sensors for detecting ambient humidity or rain             conditions. A mobile gaming device may contain light sensors             for detecting ambient brightness, cloudiness, and so on. A             mobile gaming device may contain microphones for detecting             ambient noise conditions. In various embodiments, promotions             of a certain form may be presented depending on ambient             conditions. For example, if ambient noise levels are high,             then a primarily visually-based promotion may be triggered             for presentation. If ambient noise levels are low, then a             promotion which includes audio components may be presented.             Thus, in various embodiments, a mobile gaming device, a             casino server, or another entity may determine ambient noise             levels in the vicinity of a mobile gaming device. Based on             the ambient noise levels, a promotion may be selected for             presentation. The selection process may consider whether the             promotion has audio components to it. In various             embodiments, ambient brightness levels may be used to             determine what types of promotions will be presented. If             ambient brightness levels are high, promotions with a             greater audio component may be presented. For example, in a             bright, sunlit environment, a mobile gaming device may be             more likely to present promotions with a higher audio             component. In a dim environment, a mobile gaming device may             be more likely to present promotions with more of a visual             component.             -   In various embodiments, rules, customs, regulations, and                 other conditions may determine which promotions may be                 used. For example, a mobile gaming device may be inside                 a theater where a show is in progress. In such an                 environment, a promotion with an audio component may be                 distracting to surrounding patrons of the theater. Thus,                 the mobile gaming device may determine promotions that                 have little or no audio components. It should be                 understood that selecting a promotion with no audio                 component may include selecting a promotion with an                 audio component and suppressing the audio component. For                 example, if the mobile gaming device determines that it                 should present a promotion with no audio component, the                 mobile gaming device may select a promotion that                 previously had an audio component and mute the audio                 component. Further, it should be understood that                 selecting a promotion that does not have a visual                 component may include selecting a promotion with a                 visual component and suppressing the visual component.             -   In various embodiments, the mobile gaming device may                 receive signals from a casino server describing rules,                 customs, regulations, and so on in the vicinity of the                 mobile gaming device. Based on such signals, the mobile                 gaming device may determine whether a particular                 promotion is suitable for presentation. In various                 embodiments, based on the location of a mobile gaming                 device, a casino server may instruct the mobile gaming                 device directly as to whether or not certain promotions                 may be presented. For example, the casino server may                 transmit to a mobile gaming device instructions                 explicitly forbidding the presentation of a particular                 promotion, or explicitly instructing the mobile gaming                 device to present a particular promotion.             -   In various embodiments, a casino server may send to a                 mobile gaming device promotions that are appropriate for                 presentation based on the conditions in the vicinity of                 the mobile gaming device. For example, the casino server                 may receive position information from the mobile gaming                 device. The casino server may then determine what an                 appropriate promotion is based on the location of the                 mobile gaming device. For example, if the mobile gaming                 device is located in a conference room during the time                 of a conference, the casino server may determine that an                 audio promotion is inappropriate. Accordingly, the                 casino server may only transmit to the mobile gaming                 device a promotion with a video component.             -   In various embodiments, if ambient conditions include                 rain, then a promotion for umbrellas may be shown. If                 ambient conditions include rain, then promotions for                 indoor activities (e.g., for shows) may be triggered. In                 various embodiments promotions may be suppressed based                 on ambient conditions. For example, if ambient                 conditions include rain, then promotions for outdoor                 tours may be suppressed. In various embodiments, ambient                 conditions surrounding a mobile gaming device may be                 detected by the mobile gaming device. In various                 embodiments, ambient conditions may be detected by some                 other entity, such as by a weather service. The mobile                 gaming device may receive signals about ambient                 conditions from other entities, such as from a weather                 service or such as from a casino server. The mobile                 gaming device may then use such information in                 determining which promotions to present. In various                 embodiments, a mobile gaming device may simply be                 instructed as to what promotions to present. The                 determination as to which promotions to present may be                 made by some other entity, such as by a casino server.                 The casino server, may, in turn, use information about                 ambient conditions in determining which promotions                 should be presented.         -   4.8.4. Based on the player's own stated interests. In             various embodiments, the interests of a player of a mobile             gaming device may serve to trigger which promotions are             presented at the mobile gaming device. For example, if a             player is interested in cars, promotions relating to cars             may be presented. For example, if a player is interested in             sports, promotions for sports tickets, fantasy sports             leagues, or sports memorabilia may be presented. In various             embodiments, a player's interests may be deduced in various             ways. A player may be asked about his interests. A player             may be asked about his interests when he first checks out a             mobile gaming device, when he first starts playing games at             a mobile gaming device, during the course of a gaming             session, or at any other time. A player's interests may be             deduced from the actions of a player. For example, suppose a             promotion is shown to the player. If the player responds to             the promotion, e.g., by touching the display screen in an             area labeled “touch here to get more information about this             product”, then the player may be assumed to be interested in             products related to the product which is the subject of the             promotion. Player interests may also be deduced through             other means. For example, the player may make purchases at a             retailer. The retailer may forward the name of the player to             the casino server, possibly including with the player's name             an indication of the products the player has purchased. The             casino server may then assume that the player has interest             in products similar to those purchased at the retailer.         -   4.8.5. You are in between games. In various embodiments, the             trigger for a promotion may be that a game on a mobile             gaming device has finished. For example, a particular             promotion may be best suited only to occur between games.             For example, the promotion may require the full area of the             display screen of the mobile gaming device. For example, the             promotion may require the full attention of the player. In             various embodiments, a promotion may be presented if a game             has finished and new game has not been started within a             predetermined period of time. For example, if a player has             completed a game and not started the next game in five             seconds, then a mobile gaming device may trigger the             presentation of a new promotion. A player may be more             receptive to a promotion if the player is not currently             involved in a game.     -   4.9. Poor connectivity. For example, if you can't be connected         to the server at the moment, then show an advertisement. In         various embodiments, a promotion may be presented if there is         any disruption in communication or connectivity between the         mobile gaming device and the casino server. In various         embodiments, the mobile gaming device may be required to         maintain communication with the casino server while allowing a         player to engage in gaming activities. For example, the casino         server may be required to continuously verify that the mobile         gaming device is on the premises of the casino in order for a         player of the mobile gaming device to be allowed to engage in         gaming activities. Thus, if there is a disruption in the         communication, the mobile gaming device may be prevented from         allowing the player to game. A disruption in communication might         then present a good opportunity for the presentation of         promotions, since the player may not be able to play games.     -   4.10. Amount of battery life left. In various embodiments, the         amount of battery life left in a mobile gaming device might         influence whether or not a promotion is presented. In various         embodiments, the amount of battery life left in a mobile gaming         device may influence which promotion is presented. In various         embodiments the amount of battery life left in a mobile gaming         device might influence the manner in which a promotion is         presented. Presenting a promotion may require battery power. For         example, audio associated with a promotion may require that a         speaker of a mobile gaming device be powered in order to         generate the audio output. As another example, presenting a         promotion between games may require power for illuminating the         display screen. As another example, in various embodiments,         presenting a promotion may first require downloading the         promotion from a casino server. For instance, the casino server         may transmit to the mobile gaming device image and audio files         to be played as part of the promotion. The downloading process         may require wireless communication, which may use up battery         power of the mobile gaming device. In situations where remaining         battery power is low, the conservation of such battery power         might allow a player to play extra games at the mobile gaming         device before the battery runs out. This may result in extra         revenue for the casino, as well as reduced frustration for the         player. Therefore, in various embodiments, when the power left         in a battery goes below a certain threshold, a promotion may be         suppressed. In various embodiments, when the power left in a         battery goes below a certain threshold, a promotion which         requires less battery power to present may be favored for         presentation over a promotion that requires more battery power         to present. Given two promotions of equal priority, the mobile         gaming device may be less likely to present the one which         requires more power the less battery life there is remaining. In         various embodiments, based on the battery power remaining in the         battery of a mobile gaming device, the mobile gaming device may         vary the manner in which a promotion is presented. In various         embodiments, if the battery power is low, images associated with         the promotion may be dimmed. In various embodiments, if battery         power is low, audio associated with the promotion may be played         at a low volume, or may not be played at all. In various         embodiments, if battery power is low, a promotion may be         truncated, or otherwise compressed. For example, a five-second         version of a video advertisement may be played rather than the         full-length 15-second version. In various embodiments, battery         life remaining, battery power remaining, energy remaining, and         other metrics may all be used in determining whether or not a         promotion should be presented, which of two or more promotions         should be presented, and the manner in which a promotion will be         presented. In various embodiments, if battery life is below a         certain threshold, promotions that are stored locally on the         mobile gaming device may be favored over promotions that must be         newly downloaded from the casino server or from some other         device. In this fashion, the power costs associated with         downloading a promotion may be saved.     -   4.11. Amount of money left. In various embodiments, the amount         of money a player has remaining may influence what promotion is         presented. The amount of money a player has remaining may also         influence whether or not a promotion is presented. In various         embodiments, if a player has a relatively small amount of money         left, promotions may be presented to the player which offer the         player monetary benefits or discounted gambling opportunities.         For example, if a player has less than 5 left, a promotion may         be presented to the player, offering the player 5 free spins if         he'll agree to be mailed an information packet about a new         retirement savings vehicle. In various embodiments, if a player         has a relatively large amount of money left (e.g., more than         500), then the player may be presented with promotions which         advertise relatively expensive products or services, such as         cars or jewelry.     -   4.12. Alerts and Messaging. In various embodiments, an alert or         message may be sent to player of a mobile gaming device. In         various embodiments, the same alert or message may be sent to         multiple different players of mobile gaming devices. If there         are many players using mobile gaming device, then the mobile         gaming devices may serve as an effective mass communication         medium for messages, such as messages to be communicated to         casino patrons. Various circumstances may trigger alerts or         messages. If an alert is accompanied by sounds, then the when         the alert is sent to multiple mobile gaming devices in a casino,         the sounds of simultaneous mobile gaming devices around the         casino making sounds may add emphasis and excitement to the         occasion of the alert (e.g., to the occasion where some player         has won a large jackpot).         -   4.12.1. When someone wins the progressive, every player's             mobile device can vibrate and/or beep. A message can also be             displayed on the mobile device. In various embodiments, a             first player of a mobile gaming device may be alerted when a             second player wins a significant payout. A significant             payout may include a jackpot, a top prize, a prize of more             than X amount (e.g., of more than 1000), and so on. In             various embodiments, an alert may take the form of beeping,             vibrations of the mobile gaming device, flashing lights, and             so on. An alert may indicate the name of the second player,             the amount won by the second player, the game the second             player was playing when he won, the home state of the second             player, or any other information. The alert or message may             take the form of a text message, an audio message, or any             other kind of message.         -   4.12.2. The alert can also happen in response to other             events, like a daily bonus, someone winning more than $100             on a slot machine, or any other significant event, or any             other event. In various embodiments, an alert may inform one             or more players when a drawing for a prize is about to             occur. For example, an alert may inform one or more players             when a keno drawing will occur. In various embodiments, an             alert may inform one or more players when a drawing is in             the process of occurring. The alert may inform a player of             partial outcomes. For example, an alert may be sent from the             casino server to a mobile gaming device. The alert may             detail one or more numbers which have been drawn in a game             of keno. The alert may include less than all the numbers             that are to be drawn for the game of keno. This may allow a             player who is viewing the alert to follow the game of keno             as it is in progress. In various embodiments, an alert may             inform one or more players that a drawing, chance event,             contest, or other event is about to occur, is in the process             of occurring, or has occurred. For example, a casino may run             a general promotion where three players per day who visit             the casino can win a car in a daily drawing. The drawing may             occur every day at a particular time, such as at 4:00 pm.             Accordingly, the casino may send an alert to one or more             players prior to the time of the drawing. The alert may get             the player(s) in an anticipatory mood for the drawing, and             help the drawing to have its intended effect of promoting             the casino. The casino may send an alert as the drawing is             occurring. The casino may send an alert after the drawing             has occurred. The alert may include winning names drawn, for             example. The alert may include images, and descriptions of             people who won. In various embodiments, any alerts regarding             winners of prizes, drawings, contests, or other events may             include information about the winners, such as pictures,             home towns, and so on.         -   4.12.3. The setting (what events trigger the alert) can be             configurable by the user. In various embodiments, a player             may indicate circumstances under which he would like to             receive an alert. In various embodiments, a player might             indicate triggers for an alert. A player may provide such             indications at various times. For example, when a player             first checks out a mobile device, the player may provide             indications of what types of alerts he would like to             receive. A player may provide indications when playing. For             example, a player may access a menu on the display screen of             his mobile gaming device. The menu may allow the player to             configure what alerts he would like to receive. The menu may             list categories of alerts. For example, one category of             alert may be an alert that is sent when someone a jackpot is             won. Another category of alert may be an alert that is sent             when a jackpot reaches a certain level. Another category of             alerts may be alerts that are sent when a drawing or other             event is set to occur. A player may select a category of             alert, e.g., by checking a box or selecting a menu item. A             player may also be able to configure a numerical level for a             prize before an alert will be sent. For example, a player             may specify that he would only like to receive alerts when a             payout of more than 1000 has been won in the casino. In             various embodiments, a player may configure alerts over the             internet. For example, a player may visit a web page of the             casino server. On the web page, the player may decide what             types of alerts he would like to receive. The player may             navigate menus, check boxes, enter text, or otherwise             indicate the types of alerts he is interested in receiving.             Once a player has checked out a mobile gaming device or             otherwise obtained a mobile gaming device, the player's             alert selections may be communicated to the mobile gaming             device. The mobile gaming device may thereupon only display             alerts for which the player has indicated interest.             -   In various embodiments, a player may receive an alert.                 The player may then indicate whether he would like to                 continue receiving alerts of the same type or category.                 For example, an alert may be presented to a player in a                 pop-up window. The player may check a box in the pop-up                 window indicating that he would no longer like to                 receive alerts of the type just received.         -   4.12.4. A player may be unable to deactivate alerts             following certain events (e.g., a player cannot change the             fact that the progressive win gives him an alert). In             various embodiments, a player has the option of suppressing             certain alerts. For example, a player may indicate that he             wound not like to see alerts about upcoming keno drawings.             Accordingly, the mobile gaming device of the player may             cease presenting to the player alerts about keno drawings.             In various embodiments, a player does not have the option of             suppressing alerts. For example, alerts may be presented by             the mobile gaming device of a player even if the player does             not wish to receive such alerts, and even if the player has             indicated that he does not wish to receive such alerts. In             various embodiments, a player is prevented from ignoring             alerts or other promotions by having to react in some way to             the promotions. For example, when a promotion is presented             to a player, the player may be required to press a button,             touch an area of the screen, answer a question about the             promotion, or otherwise respond to the promotion. If the             player does not respond, the player may be prevented from             playing further games on his mobile gaming device. For             example, an image associated with a promotion may occupy the             entire screen area of a mobile gaming device until the             player reacts to the promotion. Only then may the promotion             disappear and allow the player to view graphics associated             with a game.         -   4.12.5. Alerts when friends or family or group members get a             good result. In various embodiments, a player may receive             alerts or messages when one of a group of people achieves a             particular outcome. The group of people may include people             with some relation to the player. For example, the group of             people may consist of friends, family, work colleagues,             members of the same club, members of the same religious             institution, classmates, fraternity brothers, and so on. A             player may indicate to the casino server who is in his             group. For example, when first checking out a mobile gaming             device from the casino, a player may provide the names of             his fellow group members. In various embodiments, when one             member of a group indicates the names or identifiers of             other members of the group, the two or more members of the             group (e.g., all members of the group) may receive messages             or alerts relating to other members of the group. For             example, when one member of the group receives a high-paying             outcome, all other members of the group may receive alerts.             In various embodiments, alerts may be sent to a player when             a member of his group who is not using a mobile gaming             device achieves a significant or noteworthy outcome. For             example, if a fellow group member at a stationary slot             machine wins a 1000 payout, then a player may receive an             alert saying, “Your friend just won $1000!!”.             -   4.12.5.1. Sharing promotions with friends or family or                 group members after a good result. Friends may know each                 others' interests best. Accordingly, if one player is                 shown a promotion that he believes another friend would                 like, he may share the promotion with the friend (e.g.,                 by selecting the friend from a list of friends through                 an interface on the device). In some implementations,                 such sharing may be encouraged after the friend wins a                 large/progressive outcome. The sharing may allow for                 example a friend to share a promotion for an item with a                 winning friend if the first friend either wants the item                 or believes the winning friend would want the item.         -   4.12.6. Reserving poker tables. Getting alerts for poker             tables. Reserve a place in a buffet line. Reserve a taxi.             -   4.12.6.1. Tables. In various embodiments, a player may                 use a mobile gaming device to reserve a spot at a gaming                 table. Gaming tables may include poker tables, blackjack                 tables, or other tables. To reserve a spot at a table, a                 player may communicate with the casino server. For                 example, the player may use his mobile gaming device to                 access a scheduling system of the casino server. The                 scheduling system may include a Web page interface, or                 other type of interface. The scheduling system may list                 gaming tables within the casino. For example, the                 scheduling system may list a set of poker tables, each                 poker table described by the game and the betting limits                 at the table. The scheduling system may further list                 names, initials, or other identifiers for players                 waiting to play at such tables. When visiting the                 scheduling system, a player may add his name to one or                 more lists of players waiting to play at tables. For                 example, a player may add his name to a list of players                 waiting to play a game of Texas Hold'em with betting                 limits of 2 and 4 (e.g., 2-4 Texas Hold'em). Once a                 player's name is added to a list of players waiting for                 a game, the player may be eligible to sit for the game                 once all players ahead of him in the list have either                 been seated or declined to participate in the game. For                 example, as seats in a game (e.g., a game of Blackjack;                 e.g., a game of poker) open up, the player at the top of                 a list of players waiting to play in that game may be                 offered a seat at the game. The player at the top of the                 list may then be removed from the list, leaving the                 previously second player now at the top of the list.                 -   In various embodiments, a player may use a mobile                     gaming device to access a scheduling system for a                     game. The scheduling system may allow a player to                     secure a place in line for a table game, for a slot                     machine game, or for any other game. The scheduling                     system may allow a player to reserve a spot in line                     for any other event or activity for which space or                     availability may be limited.                 -   In various embodiments, a player may use a mobile                     gaming device to view available games or tables in a                     casino. For example, a map of a casino may visually                     indicate gaming tables, including which tables have                     openings for players. If there is currently an                     opening, a player may use his mobile gaming device                     to reserve the opening for himself. For example, a                     player may touch an area on a diagram of a casino                     floor. The area may be a representation of a poker                     table. Having touched the area, the mobile gaming                     device may ask the player whether he would like to                     reserve a spot at the table. The player may indicate                     affirmation by touching a button on the screen of                     his mobile gaming device, such as by touching a                     button labeled “yes”. The mobile gaming device may                     inform the player of any time limits associated with                     claiming the spot. For example, the mobile gaming                     device may inform the player that the player has 10                     minutes in which to claim the spot before the spot                     will be given to someone else. In various                     embodiments, when a player reserves a spot at a                     gaming table, the player may indicate the amount for                     which he would like to buy in at the gaming table.                     The player may indicate that amount of cash he would                     initially like to convert into gaming chips prior to                     starting play at the gaming table. The player may                     indicate the amount of gaming chips with which he                     would like to begin play at the gaming table. After                     the player has indicated a number of chips with                     which he would like to begin, a casino                     representative may arrange to have the chips placed                     at the gaming table pending the arrival of the                     player. Thus, when the player arrives at the gaming                     table, chips may have been counted out for the                     player already.                 -   In various embodiments, a player may wish to reserve                     a seat at a gaming table. However, the gaming table                     may currently be in full use. The player may                     accordingly interact with a scheduling system in                     order to place himself in line for a seat at the                     table. In various embodiments, the casino (e.g., the                     casino server) may indicate to the player an                     estimate of the amount of time it will take before a                     seat opens up for the player at the gaming table.                     For example, the casino server may transmit to the                     player's mobile gaming device an estimate that the                     wait will be one hour. The waiting time may then be                     displayed for the player on the screen of the                     player's mobile gaming device. The casino server may                     use various algorithms to estimate a waiting time.                     The casino server may have historical data                     indicating the rate at which spots open up at a                     particular type of game, at particular betting                     limits, at particular times of day, and so on. Using                     such data, and using data about the number of people                     ahead of a player for a table, the casino server may                     estimate how long it will take for a player to get a                     seat at a table. For example, the estimated time                     before a player will be seated at a table may be                     equal to the average time it takes a seat to vacate                     multiplied by one plus the number of people who are                     ahead of the player in line for a seat.                 -   In various embodiments, the casino may inform the                     player of any future gaming tables that will open                     up. For example, the casino may inform the player                     that a new poker table will be opening up in half an                     hour. The player may, accordingly, place himself on                     a wait list for the new table.                 -   In various embodiments, a player may play a game on                     a mobile gaming device. The mobile gaming device, or                     another device, may subsequently offer the player an                     opportunity to play the same game at a stationary                     gaming device and/or at a physical gaming table. For                     example, it may be assumed that if a player has                     played a game for a period of time on a mobile                     gaming device, the player might also be interested                     in playing the same game at a stationary device                     and/or at a gaming table. In various embodiments, a                     player may play a game of poker on a mobile gaming                     device. For example, the player may play a game of                     Texas Hold'em. The mobile gaming device may then                     display a message asking the player whether or not                     the player would like to sit down at a poker table                     to play a game of poker with a live dealer, with                     physical cards, and with live opponents. The player                     may indicate that he is interested. The player's                     indication of interest may be transmitted to the                     casino server. The casino server may then send                     instructions, e.g., to a casino representative, to                     have a spot at the table reserved for the player. In                     various embodiments, a player may be engaged in a                     slot machine game on his mobile gaming device, e.g.,                     the player may play a game with simulated slot                     machine reels on the display of the mobile gaming                     device. An offer may then be presented to the player                     to play the same game on a stationary slot machine.                     The player may accept the offer. The slot machine                     may be subsequently reserved for the player. In                     various embodiments, when a player plays a                     particular type of game on a mobile gaming device,                     and when a spot or space opens up for a similar game                     at a stationary gaming device or at a gaming table,                     the spot or space may be offered to the player of                     the mobile gaming device.         -   4.12.7. Win a spot at a poker table or blackjack table while             playing. In various embodiments, a player who is waiting for             a spot at a gaming table, at a game, or in some other             activity must play continuously in order to maintain his             spot in line. Continuous play may, in various embodiments,             be defined differently. For example, continuous play may             mean that a player must play one game at least every thirty             seconds. As another example, continuous play may mean that a             player must make at least 3 in wagers every minute. In             various embodiments, a player who does not maintain             continuous play may fall back in a line. For example, for             every two minute gap in the play of a player, the player may             fall back one place in line. If the player was fifth in line             for a spot at a gaming table, the player may fall back to             sixth in line for a spot at the gaming table.             -   In various embodiments, a player may win a place in line                 while playing a game. For example, a player may play a                 game on a mobile gaming device. The player may win an                 outcome which advances him one place in line for a spot                 at a gaming table. A player may also fall back in line                 based on certain outcomes. For example, a player waiting                 for a spot at a gaming table may achieve a “fall back”                 outcome when playing another game on his mobile gaming                 device. The player's place in line may accordingly fall                 back. In some embodiments, players may compete for a                 spot when the spot opens up. For example, five players                 may be waiting for a spot at a poker table. When a spot                 at the table opens up, each of the waiting players may                 play a game on his or her respective mobile gaming                 device. The player with the best performance in the game                 may get the open spot at the gaming table. For example,                 the player who wins the most money in the game may get                 the spot at the gaming table.         -   4.12.8. The act of playing as an entry into any contest or             lottery. In various embodiments, play of a game may make a             player eligible for entry into a contest or lottery. For             example, for each game played on a mobile gaming device, a             player may receive an entry into a raffle drawing for a new             car. The car may be raffled off to a player who has played a             mobile gaming device within a sponsoring casino. In various             embodiments, a player must meet a minimum threshold of play             before receiving entry into a contest or lottery. For             example, a player must play at least one hundred games to             receive entry. For example, a player must wager at least 250             in order to receive entry. In various embodiments, a player             may receive a number of entries to a contest or lottery             which is proportional to an amount the player has wagered.             For example, a player may receive entries into a drawing for             show tickets, where the number of entries is proportional to             an amount wagered by the player. In various embodiments,             play of a mobile gaming device may confer to a player entry             into a state lottery, inter-state lottery, national lottery,             and so on. In various embodiments, play of a mobile gaming             device may confer to a player entry into a contest or             lottery which is in addition to the game played on the             mobile gaming device. In various embodiments, play of a             mobile gaming device may confer to a player entry into a             contest or lottery which is independent from the game played             on the mobile gaming device.         -   4.12.9. Play poker against other people waiting for an             actual spot at the tables. In various embodiments, a player             may use a mobile gaming device to simulate play of a table             game. In various embodiments, a player with a mobile gaming             device may simulate play of a table game with or against             other players who have mobile gaming devices. For example,             several players with mobile gaming devices may compete             against one another in a game of poker. As another example,             several players with mobile gaming devices may participate             in a game of blackjack using a common dealer and a common             deck of cards, e.g., just as the players would if they were             at a physical blackjack table. In various embodiments, a             player may ask to be seated at a table or at a game. For             example, a player may ask to be seated for a poker game. The             player may be informed that there are no seats available for             the poker game. However, the player may be offered the             opportunity to play a game using a mobile gaming device. The             player may be offered the opportunity to play the same             version of poker as the one for which he had asked to be             seated. The player may, accordingly, receive the mobile             gaming device and begin play of the game of poker. When a             seat becomes available at the physical game of poker, the             mobile gaming device of the player may alert the player that             the seat has become available. For example, a casino             representative may key a message for the player into a             terminal. The message may be forwarded (e.g., via the casino             server) to the mobile gaming device of the player. The             player may thereby be informed that a spot for him at the             physical poker table is now available. In various             embodiments, a player who is waiting for a seat at a             physical gaming table may compete with a mobile gaming             device against other players with mobile gaming devices.             Players waiting for the same table may compete against one             another. For example, five players waiting for seats at a             poker table with limits of 4 and 8 may compete in a poker             game on their respective mobile gaming devices. The players             may compete on their mobile gaming devices in a game with             limits of 4 and 8. Thus, in various embodiments, players             waiting to play at a physical gaming table which features a             particular game may use mobile gaming device to play the             same or a similar game. In various embodiments, a player who             is waiting for a spot at a table may use a mobile gaming             device to play a game with or against other players who are             physically seated at the table. Thus, a player with a mobile             gaming device may play an electronic version of a game that             is being played with real cards, dice, or other playing             tokens at a physical gaming table. -   5. Indications that there is a promotion. Various signals may be     used to get a player's attention so as to inform the player that     there is a promotion for him to peruse. In various embodiments, such     signals may be generated if it is unclear whether a player would be     currently looking at his mobile gaming device. For example, if the     player has been engaged in a game in the past five seconds, it may     be assumed that the player is currently viewing his mobile gaming     device. Thus, a signal of a promotion may not be sent. However, if     the player has not been engaged in a game in the last five seconds,     a signal may be generated to indicate that a promotion is being     presented.     -   5.1. Vibration. In various embodiments, a mobile gaming device         may vibrate to indicate that there is a promotion for the         player. The vibrations may be effective if the mobile gaming         device is, for example, in physical contact with the player,         such as being in the player's pocket. In various embodiments,         vibrations associated with a promotion may be distinct from         vibrations associated with a phone call, or an email. For         example, the mobile gaming device may vibrate at one frequency         to signal an incoming call, and at another frequency to signal         that a promotion is being presented.     -   5.2. Beeping. In various embodiments, a mobile gaming device may         beep to signal that a promotion is or is about to be presented.         In various embodiments, a beep that signals the presentation of         a promotion may be distinct from a beep that signals some other         event, such as an email.     -   5.3. Ringing. In various embodiments, a mobile gaming device may         ring to signal the presentation of a promotion. The ring         associated with a promotion may be distinct from rings signaling         other events, such as a phone call. -   6. Player responds to an advertisement, e.g., the player shows     interest. In various embodiments, a player may respond to a     promotion. The player may respond in such a way as to indicate     interest in the product, service, event, etc. being promoted. The     player may express interest in buying the product or service or in     finding out more information about the product or service, for     example. The player may respond in a number of ways. During, or     following a promotion, the player may have the opportunity to press     or click on a button labeled “learn more” “get more information” or     the like. Pressing such a button, e.g., on his mobile gaming device,     may send a signal to the casino server. The casino server may then     forward more information about the product, service, event, etc. to     the player. For example, the casino may transmit to the player a     text message describing further details about a product. As another     example, the casino may transmit to the player more images of the     product or service in which the player has expressed interest. The     casino server may have further information related to a promotion     stored at the casino server. For example, information about the     subject of a promotion may be stored in a casino database in     associated with the promotion itself. The casino server may receive     further information relating to a promotion when a marketer submits     a promotion. When submitting a promotion, a marketer may provide     additional information. Additional information may include: (a)     further description of the product, service, event, or other subject     of the promotion; (b) information about where to buy the product or     service being promoted; (c) information about the company or     marketer making the promotion; (d) safety information; (e)     information about related products or services; (f) information     about other products being sold by the same company; (g) information     about other products made by the same manufacturer; (h) pricing     information for the product or service; (i) shipping information for     the product (e.g., to what states does the product ship; e.g., how     much does shipping cost); (j) information about availability of the     product; (k) information about where the product can be     purchased; (l) information about when the product or service may be     purchased; (m) reviews for the product or service; and any other     information pertaining to the promotion or to the product, service,     event, etc. being promoted.     -   6.1. More information about the product mailed or emailed to the         player. When a player expresses interest in the subject of a         promotion, further information about the subject of the         promotion may be sent to the player. The information may be sent         via electronic mail. If the information is sent via electronic         mail, the player may have a chance to look at the information         later when he is not in the midst of a gaming session. The         casino server may have the player's email address on file. For         example, the casino may have collected the player's email         address (and other contact information and other information         about the player) when the player signed up for a player         tracking card, when the player checked out his mobile gaming         device, when the player registered at the casino hotel, etc. If         the casino does not have contact information for the player, the         player may enter such information at the time he expresses         interest in a promotion. In various embodiments, additional         information pertaining to promotion may be mailed to a player at         a postal address. The postal address may be on file with the         casino, or may be provided by the player when requesting         additional information on a promotion.     -   6.2. More information shown to the player on the mobile device.         In various embodiments, if a player expresses interest in the         subject of a promotion, more information about the promotion may         be presented to the player on his mobile gaming device. More         information may be shown to the player in the form of text,         audio, video, still images, cartoons, or in any other         presentation format. The additional information may have been         previously received by the casino from the marketer, and stored         with the casino. In various embodiments, when a player expresses         interest in the subject of a promotion, the casino may transmit         to the marketer an indication that the player has expressed         interest. The marketer may then send information to the player.         The marketer may send information directly to e.g., an email         address or postal address of the player. In various embodiments,         the marketer may transmit information about the subject of a         presentation to the casino. The casino may then transmit the         information to the mobile gaming device of the player. Using his         mobile gaming device, a player may repeatedly ask for further         information about the subject of a promotion. As the player asks         for more information, more information may be transmitted to the         player's mobile gaming device and presented to the player from         the mobile gaming device.         -   In various embodiments, a player may request more             information about the subject of a promotion. However, in             order to provide additional information, a marketer may have             to pay the casino. The marketer may have to pay the casino             in order to compensate the casino for space taken up on the             mobile gaming device of the casino with the additional             information and/or for potentially diverting the attention             of the player away from the player's gaming session. Thus,             in various embodiments, when the player requests more             information, a marketer must first confirm that it wishes to             provide the additional information and must confirm that it             is willing to pay to provide such additional information.         -   In various embodiments, when a player expresses interest in             the subject of a promotion, additional information may be             presented for the player using the same slots that are used             for original promotions. For example, a promotion may be an             advertisement for a car. The promotion may consist of a             still image of the car which replaces a symbol on the reels             of a slot machine. A player may express interest in the car.             Thus, subsequently, additionally images of the car may             appear as replacement symbols. These additional images may             show the car from other angles, may show the interior of the             car, may show the car in different colors and styles, and             may show any other depiction of the car. In various             embodiments, further information provided about a promotion             may take the form of follow-on or add-on promotions.     -   6.3. More information shown to the player on a nearby slot         machine. In various embodiments, additional information related         to a promotion may be presented to a player using a nearby         gaming device. The nearby gaming device may provide a large         screen area on which to display promotions. Further the gaming         device may not be in use. Therefore, the entire screen area may         be available to display promotions. Further, the nearby gaming         device may be able to display promotions for a player even while         the player continues to play at his mobile gaming device.         -   In various embodiments, additional information shown to a             player may be shown on a stationary gaming device. However,             the player may be on the move while additional information             is being shown. For example, the player may be walking.             Therefore, in various embodiments, information shown to the             player may move so as to follow the player. For example, a             player may walk alongside a row of slot machines. When the             player is in front of a first slot machine, the first slot             machine may display a promotional message. As the player             walks, he may become more near to a second slot machine and             less near to the first slot machine. Accordingly, the second             slot machine may now display the same promotional message.             The message may disappear from the first slot machine.             Accordingly, the message may follow the player. Information             shown to the player may be shown on the nearest available             stationary gaming device to the player at any given time. An             available gaming device may include a gaming device that is             not in use, a gaming device that has capabilities to display             information of the type necessary, and so on. In various             embodiments, information shown to the player may be             displayed on the nearest available stationary gaming device             to the player that is also facing in the direction of the             player. In various embodiments, a display of information may             transfer from one gaming device to another according to             which gaming devices are adjacent to one another. For             example, a player may walk with two gaming devices to his             left. As he walks, a display may move from a first of the             gaming devices to a second of the gaming devices. In the             meantime, the player may walk near to a gaming device that             is on his right. However, the display of information may be             maintained on the gaming devices to the player's left so as             to provide a more continuous viewing experience and so as to             avoid making the player turn his head from left to right.             The location of the player may be tracked in various ways so             that information about promotions may be displayed near to             the player. For example, the mobile gaming device of the             player may communicate its location to the casino server.             The casino server may thereby deduce the location of the             player, assuming the player is currently holding the mobile             gaming device. In various embodiments, more information             related to a promotion may be shown to a player on a             stationary gaming device only if the player plays at the             gaming device. For example, additional information may be             shown to the player only if the player makes bets in at             least three games every minute.         -   In various embodiments, a player may be presented with             additional information related to a promotion, the             additional information presented at a stationary gaming             device. After the additional information has been presented             to the player, the player may be encouraged to begin play at             the stationary gaming device. For example, the stationary             gaming device may display a message for the player saying,             “Hey, while you're here, how would you like to play a few             games.” The stationary gaming device may even offer the             player an incentive to play at the stationary gaming device.             For example, the stationary gaming device may present a             message to the player saying that if the player makes 8             spins at the stationary gaming device, then the last two             spins will be free.         -   In various embodiments, additional information related to a             promotion may be presented, on a stationary gaming device to             a first player with a mobile gaming device. The stationary             gaming device may be chosen from among several stationary             gaming devices, e.g., from stationary gaming devices that             are all within a predetermined distance of the first player.             Additionally, the stationary gaming device may chosen so as             to be near to a second player. The second player may be a             player who is at an adjacent stationary gaming device to the             one being used to present the additional information about             the promotion.     -   6.4. Casino attendant brings more information to show the         player. In various embodiments, a casino attendant may bring to         a player of a mobile gaming device additional information about         the promotion. For example, the player may use his mobile gaming         device to request additional information. The casino server may         then send a page or email notification to a casino         representative to go find the player. The casino server may         indicate to the casino representative the location of the         player. For example, the casino server may indicate that the         player is near to a stationary gaming device number 924, or that         the player is near to the east entrance. The casino         representative may, in any event, find the player. The casino         representative may bring additional information related to the         promotion. The additional information may include brochures,         coupons, paper advertisements, gift certificates, or any other         information. The additional information may include storage         media, such as universal serial bus drives, CDs, DVDs, and so         on. In various embodiments, the casino attendant may bring to         the player a sample of the product. For example, if the         promotion is for a new lipstick, the casino representative may         bring to the player a sample of the lipstick.     -   6.5. Player information sent to the marketer. In various         embodiments, player information may be sent to a marketer. The         player information may be sent to the marketer who originated         the promotion sent to the player. The player's contact         information may be forwarded to the marketer so that the         marketer may later contact the player to provide the player with         more information about the product.     -   6.6. More information delivered to the player where he is (e.g.,         by a casino representative). A person may deliver information         (e.g., a pamphlet, etc.) to a user directly using a location or         the mobile gaming device to find the user. In addition to or as         an alternative to delivering a physical embodiment of the         information, the person may discuss the information verbally         with the user. In some implementations, the person may take the         user to see a product (e.g., take a test drive of a car, see a         piece of jewelry, etc.).     -   6.7. More information left for the player in his casino hotel         room. Information may be sent to a hotel room of a player. For         example, upon a next cleaning, information may be left in the         room, information may be placed under a door, etc.     -   6.8. More information for the player when he checks out of the         hotel (e.g., a departure package). When a player checks out,         information may be given to the player at a front desk. -   7. Reformatting an advertisement that was meant for a big slot     machine screen for a mobile device screen. Some embodiments may     allow an advertiser to use a single advertisement for multiple     displays. For example, an advertiser may submit an advertisement     that for use on a large monitor, a physical slot machine, and so on.     The advertisement (e.g., image, video, sound, etc.) may be converted     for use on one or more other devices, such as a mobile gaming     device. Conversion may include converting formats, converting size     of images, converting amount of storage size needed (e.g.,     compressing, lowering fidelity, lowering resolution, etc.),     converting colors, and so on. By so converting, an advertiser may     have an easier time interfacing with the devices because the     advertiser would not need to submit an advertisement formatted for     each possible device. -   8. Showing marketers available marketing opportunities (e.g., who is     playing now). In various embodiments, the casino server may show to     potential marketers a current audience that is available for viewing     promotions. The current audience may include players currently     gaming on mobile gaming device, players in possession of mobile     gaming devices, players with money remaining with which to play on     mobile gaming devices, people within viewing range of mobile gaming     devices (e.g., people who might be able to see a promotion shown on     a mobile gaming device, people within hearing range of an mobile     gaming device, and so on. A potential audience may include people     within a limited geographic region. For example, a marketer with     retail stores in Nevada might only be interested in sending     promotions to people currently in Nevada. A potential audience may     include only people within a certain age range. For example, a     casino server may show to a marketer only people between the ages of     18 and 35, as such people may be the marketer's main target     audience. In various embodiments, a potential audience may include     only people with certain demographic characteristics, such as only     married people, such as only French speakers, such as only people     with incomes over $150,000, and so on. A potential audience may be     presented to a marketer in the form of one or more aggregate     statistics. For example, a marketer may be told that there are     currently 3500 people playing mobile gaming device who are between     18 and 25 years old.     -   In various embodiments, a potential marketer may be shown         available advertising mediums. For example, a marketer may be         told that there are currently 1258 places where their product         logo can be used as a symbol on reel. As another example, a         marketer may be told that there are currently 100 slots open         where promotions will be inserted between games played on mobile         gaming devices. As will be appreciated, any statistic describing         available slots or media for promotions may be presented to a         marketer.     -   In various embodiments, a marketer may be shown available slots         for promotions for a particular target audience. For example, a         marketer may be told that there 200 mobile gaming devices in         which the marketer's promotion may be used in background         graphics and where the mobile gaming devices are being played by         players of the marketer's target audience.     -   8.1. The number of active handhelds nationwide is tracked. In         various embodiments, the casino server may track the number of         mobile gaming device that are currently in use across a         particular location or geographic region. The casino server, for         example, may track the number of mobile gaming device active         within a room, within a casino, within a neighborhood (e.g., the         Las Vegas strip), within casinos of the same management, within         a state, or within an entire country. Thus, in various         embodiments, a casino server may track the number of mobile         gaming devices in use nationwide. A statistic describing the         number of active mobile gaming devices may be presented to a         marketer.         -   8.1.1. How many handhelds of a particular demographic. In             various embodiments, the casino server may track the number             of mobile gaming devices that are being used by players of a             particular demographic. For example, the casino server may             count 584 people that are using mobile gaming device and who             are between the ages of 60 and 65. As another example, the             casino server may count 2690 people that are using mobile             gaming devices and who are also gun owners.         -   8.1.2. How many handhelds playing a particular denomination.             In various embodiments, a casino server may track the number             of mobile gaming devices on which players are playing games             of a certain denomination. For example, the casino server             may track the number of mobile gaming devices on which             players are playing games with required wagers of $1.             -   In various embodiments, the casino server may track the                 number of mobile gaming devices on which a particular                 type of game is being played. For example, the casino                 server may track the number of mobile gaming devices on                 which Triple Play Video Poker is being played. In                 various embodiments, the casino server may track the                 number of mobile gaming devices on which games by a                 certain game developer are being played.             -   In various embodiments, any group that is tracked may                 have its playing characteristics represented by one or                 more statistics. Such statistics may be presented to a                 marketer. Based on such statistics, a marketer may                 decide whether or not to promote to the group.     -   8.2. Space is made instantly available. In various embodiments,         slots, space, or media for promotions may be made available to         marketers in a rapid, instant, or real-time basis. For example,         a marketer might make a decision to have a promotion presented         one minute before it is actually presented. The central server         may, for example, list available slots for promotions into the         future. A marketer may browse such available slots. The marketer         might select one or more slots, even if such slots are to occur         within minutes or less. The promotion may then occur on         schedule. If a marketer's promotion is not already stored with         the casino server (e.g., if image and audio data is not already         stored with the casino server), the marketer may be required to         upload a promotion to the casino server before it can be         presented. Once uploaded, a promotion may be transmitted from a         casino server to one or more mobile gaming devices for         presentation.     -   8.3. We allow advertisers to immediately distribute ads on the         fly to all, or to all that meet certain criteria. Immediate         means display this and now. In various embodiments, a marketer         may specify one or more criteria. The criteria may include         criteria defining a target audience, such as demographic         criteria. The criteria may also define games being played,         outcomes achieved, and so on. The criteria may also define         current locations of the target audience. For example, the         criteria defined by a marketer may specify that the target         audience includes only people within the state of Mississippi.         Once a marketer has specified a target audience, or criteria         that a member of the target audience must meet, promotions from         the marketer may be presented to the target audience. Promotions         may be presented to all of the target audience, or to some         fraction of the target audience. For example, 1000 people may         currently satisfy criteria defined by the marketer. The         promotion of the marketer may, accordingly, be presented to all         1000 people meeting the criteria. In some embodiments, however,         the marketer may not wish to pay to reach the entire target         audience. Instead, for example, the marketer may decide to pay         to reach only a fraction of the target audience, such as one         third of the target audience. Once a marketer has defined a         target audience for a promotion, the promotion may be presented         to members of the target audience substantially immediately.         Alternatively, the promotion may be presented to members of the         target audience at a later time, such as at a time desired by         the marketer.     -   8.4. Advertisers get to see a list of who is located near to the         product, e.g., to a coke store. In various embodiments, a         marketer may view data indicative of how many players of mobile         gaming devices are near to the product of the marketer. For         example, a marketer may wish to see a count of the number of         players of mobile gaming devices who are near to a fast food         restaurant which the marketer represents. The marketer may then         decide whether to have a promotion presented to some or all of         such players.     -   8.5. Mechanism to allow advertisers to find out what's available         and to insert bids. The advertiser has a mechanism to acquire an         advertising block. An advertiser has a mechanism to place an ad         in the black. In various embodiments, a marketer may view a list         or other description of available slots or media in which         promotions may be inserted. The list may include a list of slots         by time of day, by game, by game denomination, by demographic of         the player, and so on. For example, a listing of a slot may         indicate that there is a 5-second slot open for 500 gamers         between the ages of 50 and 55. The marketer may have the         opportunity to purchase that slot and to have his promotion         presented during that slot. Thus, the marketer may have his         promotion presented to 500 gamers. The marketer may be able to         place a bid for that slot. A marketer who places the highest bid         may have the opportunity to have a promotion placed in a slot.         In various embodiments, a marketer may be able to have a         promotion presented to a first number of gamers. The marketer         may submit the high bid to have a promotion presented to a         second number of gamers, where the second number of gamers is         less than the first number of gamers. For example, 500 gamers         may be currently playing mobile gaming devices. A marketer may         bid to have his promotion presented to 200 of the gamers. If the         marketer has submitted the high bid, the marketer may succeed in         having his promotion presented to the 200 gamers. The marketer         who has submitted the next highest bid may have the opportunity         to have his promotion presented to gamers from among the         remaining group of gamers. Thus, in various embodiments, a         marketer may submit a bid where the bid includes not only a time         of day, a game, a length of a promotion, a size of a promotion,         etc., but also a number of players to which the promotion will         be presented.         -   In various embodiments, a marketer may purchase a slot for a             promotion or submit bids to have a promotion placed using a             Web site of the casino server. The casino server Web site             may list available slots, highest bids, any restrictions on             which types of promotions may be shown, and so on. The             marketer may use the Web site to submit bids, to make             purchases, to make payment (e.g., by submitting a credit             card number), to submit the actual promotion (e.g., image             data; e.g., video data; e.g., audio data), and so on. A             marketer may submit bids and other information in many other             ways, as will be appreciated. For example, a marketer may             submit bids via phone, fax, email, postal mail, and so on.         -   Bidding may take place over time. In some implementations,             the bidding for a slot may continue until the time for that             slot occurs. As the time for the slot nears, more             information about the slot may be known (e.g., information             about what players are in the area, information about how             much those players have won, and so on). Accordingly,             bidding on slots may accelerate as the time of the slot             draws near. Real time bidding may be used so that bidders             may quickly submit bids at any time up to the time of the             slot and the slot may automatically be filled at the time of             the slot by the highest bidder who may be automatically             charged. Bidders may be authorized up to a maximum bid             amount before a bid begins. In some embodiments, automatic             betting, reverse auction methods, automatic buyout levels,             and/or any other auction methods may be used. For example,             in one implementations, bidders may submit their highest             levels up to the end of the auction time and the bidder with             the highest level may win the auction at the price of the             bidder with the second highest level. In some embodiments,             one or more derivative markets regarding slots may be             formed. For example, a futures market for slots may be             created. The futures market may allow trading of futures use             of a slot. For example, a purchaser of a futures contract             may be purchasing the right to use the slot at the time of             the slot. If the price of the slot increases above the price             paid for the future, the seller of the futures contract may             lose the difference and be required to purchase the slot for             the use of the purchaser of the futures contract. If the             price of the slot does not increase to above the price paid             for the future, the seller of the futures contract may make             the difference between and be required to purchase the slot             for use of the purchaser of the futures contract.             Accordingly, who believe they have knowledge of the prices             of slots may buy and sell futures based on that knowledge.             In some embodiments, a same entity that sells the slots may             also sell the futures.     -   The advertisers may be able to specify the parameters of         displaying their ads—for how much money, to whom, in what games,         when, & in what context. In some embodiments, advertisers may         create advertising campaigns. Advertising campaigns may set         parameters for when a promotion should be displayed (e.g., after         X, Y, Z events, to people in A, B, C demographic groups, etc.),         in certain games, on certain devices, and so on. A duration of         the campaign may be specified. An amount of money to be spent on         a campaign may be specified. The advertiser may be charged for         each display of the promotion up to the amount of money or the         end of the duration and the campaign may then be ended. In         certain embodiments, more directed ads (e.g., ads with more         restriction on who and when they should be viewed) may cost more         per running. In some embodiments, ads related to popular         demographic groups and or events may cost more. In some         embodiments, a maximum and/or minimum cost per display of an ad         may be a parameter of a campaign. -   9. Pricing schemes for advertisers. In various embodiments, the     casino may charge marketers a variable price for presenting the     marketers' promotions. The price charged may depend on a number of     factors.     -   9.1. By real-estate space. The price of a promotion may depend         on the amount of physical space taken up by the promotion. The         physical space taken up may include space taken up on a display         screen. For example, a first promotion that takes up 1 square         inch may cost 5 cents per viewer, while a second promotion that         takes up 4 square inches may cost 15 cents per viewer. Physical         space may be measured in a number of ways. Physical space may be         measured in square inches, square centimeters, in pixels, and in         portions or percentages of total screen space (e.g., a promotion         may take up 25% of the space of a display screen; e.g., a         promotion may take up 2 quadrants of a display screen). Physical         space may be measured in terms of other items. For example,         physical space may be measured in terms of symbols. Thus, for         example, a promotion may take up the space of two symbols. In         various embodiments, the price of a promotion increases         monotonically with the amount of space taken up by the         promotion, all else being equal. A promotion may take up space         in the sense that images associated with the promotion take up         space. For example, the space taken up by a promotion may be the         space taken up by images or videos associated with the         promotion.     -   9.2. By time shown. In various embodiments, the price of a         promotion may depend on the amount of time taken up by the         promotion. For example, a promotion may be presented for 1         second, five seconds, or for thirty seconds. For example, an         image associated with a promotion may be displayed for 1 second,         five seconds, or for thirty seconds. A promotion which is         presented for a longer period of time may cost more money for a         marketer.     -   9.3. By which customers got to see the ad. In various         embodiments, the price of a promotion may depend on the target         audience for the promotion. The price of a promotion may         increase as the income level of the target audience increases.         The price of a promotion may increase as the average bet amount         of the target audience increases. The price of a promotion may         increase as the skill level of the target audience increases.         The price of a promotion may increase as the age of the target         audience decreases. The price of a promotion may be higher for a         target audience of city dwellers versus suburban dwellers. In         various embodiments, a target audience may include a set of         players who have achieved similar results. For example, a target         audience may include all players who have won money in the last         hour. In various embodiments, the price of a promotion may be         higher for a target audience of players who have won money in         the last hour than for a target audience of players who have not         won money in the last hour. In various embodiments, a marketer         may pay more to reach people who have had better luck (e.g., in         the form of winning outcomes) than to reach people who have had         worse luck (e.g., in the form of losing outcomes). In various         embodiments, the price of a promotion to jackpot winners may be         higher than the price of a promotion to people who have not won         jackpots, or to people who have not just won jackpots.     -   9.4. Advertisers are charged more for customers with more money.         In various embodiments, the price of a promotion may depend on         the amount of money that the viewing audience has. A promotion         that is shown to a player with a credit balance of 900 may cost         the marketer more than a promotion that is shown to a player         with a credit balance of 40. A promotion that is shown to a         player with income of 200,000 may cost the marketer more than         does a promotion that is shown to a player with an income of         50,000. A promotion that is shown to a player with a hotel room         costing 300 per night may cost the marketer more than does a         promotion that is shown to a player with a hotel room costing         $50 per night.     -   9.5. Advertisers are charged more for customers with particular         demographics. In various embodiments, the price of a promotion         may depend on one or more demographics of the target audience.         For example, a marketer may have to pay more to show a promotion         to a player with one child than to a player with two children.     -   9.6. There can be a straight price. In various embodiments, the         price of a promotion with certain characteristics (e.g., to be         presented to a particular target audience, for a particular         period of time, etc.) may be fixed. That is, the price may be         posted and may not be subject to change or negotiation. The         price may be quoted in various ways. For example, the price of a         promotion may be quoted on a per-player basis (e.g., the price         of a promotion is 5 cents per player to which it is shown). The         price of a promotion may be quoted on the basis of a block of         players who are to view the promotion. For example, the price of         a promotion may be quoted as the price to show a promotion to         500 people.     -   9.7. There can be a bidding process. If a marketer is the         winning bidder, the marketer gets the ad space. In various         embodiments, marketers may bid against one another for the         opportunity to present a promotion. An opportunity to present a         promotion may include an opportunity to present a promotion         under a particular set of circumstances. The circumstances for         presenting a promotion may include one or more of the         following: (a) a time of day during which the promotion will be         presented; (b) a player to whom the promotion will be         presented; (c) a set of players to whom the promotion will be         presented; (d) a game with which a promotion will be presented         (e.g., a promotion will be presented on the face of a card in a         game of video poker); (e) an amount of time for which the         promotion may be presented; (f) an amount of space that will be         taken up by a promotion; (g) a type or model of mobile gaming         device on which the promotion will be presented (e.g., the         promotion may be presented on a model of mobile gaming device         with a particular large and bright screen); (h) a location in         which a promotion will be presented (e.g., a promotion may be         presented only to players who are in a particular restaurant;         e.g., a promotion may be presented only to players who are         within 20 feet of a particular jewelry store; e.g., a promotion         may be presented only to players who are by the pool); and any.         As will be appreciated, the circumstances surrounding the         presentation of a promotion may influence the desirability of         presenting the promotion, and may thus influence the amount that         a marketer might be willing to pay to present the promotion.         -   In various embodiments, marketers may bid for the             opportunity to present a promotion under a particular set of             circumstances. For example, the casino may post a set of             circumstances. The posting may allow a marketer to present a             30-second promotion on 4 square inches of screen space,             sometime between 2:30 pm and 2:35 pm on Sunday, to 300             female players aged 35-55. In other words, the winning             marketer's promotion would be shown to 300 different players             as described, with each promotion shown to a player on her             respective mobile gaming device.         -   When the opportunity is posted, marketers may have the             opportunity to bid so as to present a promotion under the             posted circumstances. Marketers may become aware of the             posting by checking a web page of the casino server. For             example, marketers may register with the casino server and             may thereby receive access to a Web site where opportunities             to present promotions are presented. In various embodiments,             marketers may become aware of the opportunity through an             email or other alert sent by the casino. For example,             anytime the casino posts an opportunity for presenting             promotions, the casino may alert marketers on its mailing             list of the opportunity.         -   A marketer may enter, in various ways, a bid for an             opportunity to present a promotion. In various embodiments,             a marketer may key in a price he would be willing to pay.             The marketer may key his bid into a Web page run by the             casino server. In various embodiments, a marketer may phone             a casino representative to convey his bid. In various             embodiments, a marketer may submit a bidding strategy to the             casino. For example, the bidding strategy may dictate that             the marketer will always place a bid that is 10 higher than             any competing bid, until the bidding level reaches 300.             Accordingly, the casino may enter bids for the marketer             automatically in keeping with the marketer's bidding             strategy.         -   In various embodiments, a marketer may bid for only a             portion of the promotional opportunities being offered. For             example, the casino may post an opportunity to display a             still image to 300 people from the Midwest between 3:00 pm             and 3:05 pm. A marketer may wish to have a promotion             presented to Midwesterners between 3:00 pm and 3:05 pm.             However, the marketer may wish to promote to only 100             people. Accordingly, the marketer may bid for the             opportunity to present a promotion to 100 of the 300 people             from the Midwest. Another marketer may wish to present to             only 200 people from the Midwest between 3:00 pm and 3:05             pm. Therefore, it is possible that both the first marketer             and the second marketer get their wishes. In various             embodiments, all winning bidders pay the same price per             person. For example, a marketer who successfully bids to             have a promotion presented to 200 of 300 people available             may pay the same price per person as does a marketer who             successfully bids to have a promotion presented to 100 of             300 people available. The amount paid per person by both             marketers may be based on the lower bid. The amount paid per             person by both marketers may be based on the higher bid. The             amount paid per person by both marketers may be an average             or weighted average (e.g., where weightings are proportional             to the number of people who will view the each of the             marketers' respective promotions) of both bids.     -   9.8. An advertiser has an exclusive to a particular “slot” (a         medium like a card). The advertiser may pay extra for this. In         various embodiments, a marketer may gain exclusive use of a         slot, medium, or other advertising venue or opportunity. A         marketer may gain exclusive rights to: (a) a particular mobile         gaming device (e.g., a marketer may have exclusive rights to         present promotions on the particular mobile gaming device for         some period of time); (b) a particular symbol (e.g., a marketer         may have exclusive rights to present promotions on the jack of         spades; e.g., a marketer may have exclusive rights to present         promotions at the third symbol position of the second reel of a         gaming device); (c) a particular area of a screen (e.g., a         marketer may have exclusive rights to present promotions in the         upper right corner of a display screen of a mobile gaming         device; e.g., a marketer may have exclusive rights to present         promotions below the playing area on a display screen of a         mobile gaming device); (d) a particular display monitor (e.g., a         marketer may have exclusive rights to present promotions on a         display monitor located above a heavily trafficked corridor in a         casino); (e) a particular gaming device (e.g., a marketer may         have exclusive rights to present promotions on a particular         gaming device; (f) a particular location (e.g., a marketer may         have exclusive rights to present promotions to players when the         players are at a certain location); (g) a particular time of day         (e.g., a marketer may have exclusive rights to present         promotions during a particular time of day); (h) a particular         group of people (e.g., a marketer may have exclusive rights to         present promotions to a particular demographic of people in a         casino; e.g., a marketer may have exclusive rights to present         promotions to a defined set of people, such as the Jones family;         e.g., a marketer may have exclusive rights to present promotions         to any person who has won more than 500 in the last hour); or to         any other category of promotional opportunity.         -   In various embodiments, when a marketer gains exclusive use             of a slot, medium, or other advertising venue or             opportunity, other marketers may be excluded from presenting             promotions in the venue while the period of exclusivity             persists. In various embodiments, the marketer with             exclusive rights may allow other marketers to present             promotions at his discretion.         -   The marketer who allows other marketers to present             promotions may receive fees from the other marketers.         -   In various embodiments, a marketer may pay extra for the             exclusive right to use a particular slot, medium, venue,             etc. For example, suppose the cost per square inch per             minute of promotional space on a mobile gaming device is             ordinarily 10 cents. If a marketer desires to purchase every             square inch of screen space on a mobile gaming device for an             hour, the marketer may pay 12 cents per square inch per             minute.         -   In various embodiments, a marketer may gain exclusive rights             to a particular slot, medium, venue, etc., with respect to a             group of marketers. The group of marketers may be a group of             competing marketers, for example. For example, a marketer             may gain the exclusive right to present promotions related             to airlines on a particular mobile gaming device. As another             example, a marketer may gain the exclusive right to present             promotions related to food during the hour of 12:00 pm to             1:00 pm on all mobile gaming devices within a casino. In             various embodiments, a marketer may pay extra for exclusive             rights to present a particular type of promotion, or for             rights to exclude a particular group of other marketers from             presenting promotions.     -   9.9. Where several advertisers want a slot, every time the slot         appears in a game one of the ads is selected at random. An         advertiser can pay more to have a greater probabilistic         weighting applied to his ad. For example, if four advertisers         pay 2, 5, 6 and 10 respectively, then their respective weights         can be 2/23, 5/23, 6/23 and 10/23. In various embodiments, a         marketer may pay for a chance or probability of having his         promotion presented. For example, a marketer may pay 5 cents and         thereby have a 50% chance of having his promotion presented in a         particular slot. In various embodiments, various marketers may         pay to have a promotion presented in the same slot. For each         marketer, a chance that the promotion will be presented in that         slot may be determined. For example, the chance that marketer         1's promotion will be presented may be determined to be 40%, the         chance that marketer 2's promotion will be presented may be         determined to be 20%, and the chance that marketer 32's         promotion will be presented may be determined to be 20%. The         chance that each marketer's promotion will be presented may be         based on the amounts paid by each marketer. In various         embodiments, the chance that a marketer's promotion will be         presented is set in proportion to the amount paid by the         marketer. Thus, if marketer 1 pays twice as does marketer 2 to         have his promotion presented in a particular slot, then the         chance that marketer 1's promotion will be presented may be set         twice as high as that of marketer 2. In various embodiments, a         slot may include a number of presentation opportunities. For         example, a slot may include an opportunity to present a         promotion to 100 people during a particular five-minute time         window. If multiple marketers pay to have a promotion presented         during the same slot, the presentation opportunities may be         divided among the marketers. For example, one marketer may         present his promotion to 60 of the 100 people, while another         marketer may present his promotion to 40 of the 100 people. In         various embodiments, the number of presentation opportunities         given each marketer may be proportional to the amount paid by         the marketer. For example, if marketer 1 pays 7, and marketer 2         pays 3, then marketer 1 may have his promotion presented to 70         people while marketer 2 may have his promotion presented to 30         people.         -   In various embodiments, a slot may include an opportunity to             present a promotion on (or in place of) a particular symbol             when the symbol arises in a game. As will be appreciated,             the symbol may arise multiple times over the course of             multiple games. If multiple marketers pay to have a             promotions presented in that slot, then one of the             marketers' promotions may be chosen at random each time             there is an opportunity arises (e.g., each time the symbol             arises in a game). The probability that a marketer's             promotion will be presented each time an opportunity arises             may be proportional to the amount paid by the marketer. In             various embodiments, the promotions presented may alternate             among all marketers who have paid to have promotions             presented in a particular slot. Marketers who have paid more             may have their promotions presented more frequently. For             example, suppose a first marketer has paid twice as much as             a second marketer to present promotions in a particular             slot. Then, for every three opportunities to present             promotions in that slot, the first marketer may be given the             first and third opportunities, while the second marketer may             be given the second opportunity.     -   9.10. There can also be a secondary market for ad space. The ad         space can be transferred, for example, with the central service         getting a small cut. In various embodiments, a marketer may         purchase slots, venues, etc. directly from the casino. In         various embodiments, a first marketer may purchase slots,         venues, etc. from another marketer or from any other third         party. In various embodiments, slots, venues, and other         promotional opportunities may be purchased and resold. A         secondary market may exist for promotional opportunities.         -   In various embodiments, the casino may run an exchange for             promotional opportunities. In various embodiments, the             exchange may be run by a third part. In various embodiments,             the exchange may have no individual governing authority. The             exchange may allow a marketer to post offers to sell             promotional opportunities. The exchange may allow a marketer             to post offers to buy promotional opportunities. Offers to             buy may include quantities and prices. For example, an offer             to buy may specify a number of people to which a promotion             will be presented as well as a price that will be paid for             the promotional opportunity. Likewise, an offer to buy may             specify a price and quantity as well.         -   In various embodiments, offers to buy and offers to sell may             include descriptions of the opportunity being bought or             sold. A description may include: (a) a number of people to             which a promotion will be presented; (b) a time of day             during which the promotion will be presented; (c) a number             of mobile gaming devices on which the promotion will be             presented; (d) the demographic of the people to whom the             promotion will be presented; (e) the amount of time that the             promotion will occupy (e.g., the promotion must be a             30-second spot) (f) the form of the promotion (e.g., still             image; e.g., video; e.g., audio); (g) the amount of screen             or display space the promotion may occupy; (i) the game that             the promotion will accompany (e.g., the promotion will be             made while players play video poker; (j) the symbol that a             promotion will represent or replace (e.g., the promotion             will represent a jackpot symbol); and any other descriptors             of promotions or the circumstances under which promotions             will be presented.         -   The description of the opportunity being bought or sold may             be provided by the casino. The casino may, in fact, be the             originator of the opportunity and so may possess a             description of the opportunity which it has come up with. In             various embodiments, each opportunity may receive a unique             identifier. For example, the opportunity to promote to 100             people between the ages of 55 and 65, each with incomes over             100,000, between 11:00 am and 11:05 am in a 30-second video             spot taking up half of a screen may have a unique identifier             of 1112223453. In various embodiments, identical or fungible             opportunities may receive the same identifier. For example,             the opportunity to present to a first person from Tennessee             at 9:00 pm may be indistinguishable from the opportunity to             present to a second person from Tennessee at 9:00 pm. Thus             the two opportunities may have identical identifiers.             However, any opportunity which is different in some way may             receive a different identifier. Associated with each             identifier may be a description of the opportunity. A             marketer who is interested in purchasing a particular             opportunity, for example, may use the identifier associated             with the opportunity to access a description of the             opportunity. For example, the casino may store a database             containing descriptions of opportunities in association with             identifiers. If a marketer submits an identifier to the             database, the casino may retrieve the description and             present the description to the marketer. The description may             be presented to a marketer, e.g., on a Web interface to the             exchange.         -   In various embodiments, a quantity specified by a marketer             may refer to a number of a particular opportunity that is             associated with an identifier. For example, a marketer may             wish to purchase 100 of the opportunity with             identifier 1112223999. This may correspond to the             opportunity to present a still image to 100 people who are             in a particular restaurant at a casino between the hours of             12:00 pm and 2:00 pm on Sunday.         -   In various embodiments, an opportunity may include the             opportunity to present a 10-second video clip to a             particular individual sometime between 6:00 pm and 9:00 pm.             There may be 100 such opportunities available, meaning that             the same individual will have 100 10-second video clips             presented on his mobile gaming device between 6:00 pm and             9:00 pm. However, as the particular times that the video             clips are presented may be chosen at random, each individual             opportunity from among the 100 may be a priori             indistinguishable from each other opportunity. Therefore             each of the 100 opportunities may have the same identifier.             Thus, for example, a marketer may bid on 10 such             opportunities to present to the player. If the marketer             should find a seller to give him the 10 opportunities, the             marketer would have the ability to present 10 10-second             video clips to the person sometime between 6:00 pm and 9:00             pm.         -   In various embodiments, one purpose of the exchange may be             to match buyers and sellers of the same opportunity. If a             buyer bids a certain price for a certain quantity of a             particular opportunity, and a seller offers the same price             for the same quantity of the same particular opportunity,             the buyer and seller may be matched. A sale may take place.             The buyer may thus acquire the opportunities to present             promotions, and the seller may give up such opportunities.             In exchange, the seller may receive payment from the buyer             based on the bid and offer amounts. The casino, or other             authority in charge of the exchange may receive a             transaction fee for matching the buyer and seller. For             example, the casino may receive a transaction fee from             either the buyer, seller, or both. The fee may come from the             last of the buyer or seller to match the price of the other.             The fee may come from the first of the buyer and seller to             post the price at which the transaction took place. The fee             may take the form of a percentage of the sale price, and may             be deducted from the amount that the seller collects from             the buyer.         -   In various embodiments, a potential buyer may pay a fee just             for posting a bid. In various embodiments, a potential             seller may pay a fee just for posting an offer. In various             embodiments, participants in the exchange may pay a fixed             fee, a fixed fee per period of time, or a fixed fee per             transactions completed, in order to participate on the             exchange.         -   When an opportunity has come into the hands of a buyer, the             buyer's name or other identifying information may be stored             in association with the opportunity. Thus, the casino may             maintain a record of which marketers own which opportunities             for presenting promotions. When it comes time for presenting             promotions, the casino may allow the owners of the             promotional opportunities to present their promotions during             those times.         -   In various embodiments, an owner of a promotional             opportunity must submit a promotion to the casino within a             predetermined time of coming into possession of the             opportunity. For example, within 1 hour after buying a             promotional opportunity, a buyer may be required to submit             an advertisement to the casino. The casino may subsequently             approve the advertisement before it can be shown. In various             embodiments, an owner of a promotional opportunity must             submit a promotion to the casino within a predetermined             period of time of the promotion's showing, or first             potential showing. For example, suppose a promotion has a             10% chance of being shown as early as 8:00 pm. Then the             owner of the promotional opportunity may be required to             submit the promotion by 7:00 pm. If the promotion is not             submitted on time, the owner of the promotional opportunity             may lose the opportunity and may be unable to have his             promotion shown. In various embodiments, if an owner of an             opportunity does not submit his promotion in time, the             opportunity may return to the market, for potential             acquisition by a new owner.         -   In various embodiments, contingency opportunities for             presenting promotions may be sold. A contingency opportunity             may include ability of a second marketer to present a             promotion if a first marketer with priority over the second             marketer decides not to present a promotion. For example, a             first marketer may purchase the opportunity to present a             promotion to a particular person at a particular time. A             second marketer may purchase the opportunity to present to             the same person at the same time if the first marketer does             not.         -   In various embodiments, an identifier for an opportunity may             include a ticker symbol. The ticker symbol may be a compact             way of representing or identifying the opportunity. For             example, the ticker symbol may consist of four letters.         -   Futures         -   [Do futures make sense in this context? There is no cost of             carry. So a future is the same as the underlying in value at             least?]     -   9.11. By the presentation means (audio versus video). In various         embodiments, the price of a promotional opportunity may depend         on the type of signal used to broadcast the promotion. For         example, promotions that employ visual or light based         presentations may be priced differently than promotions that         employ audio or sound based presentations. A promotion that uses         video and audio may be priced differently than is a promotion         which uses only video. A promotion that uses video and audio may         be priced differently than is a promotion which uses only audio.         A promotion which uses vibrations or other touch stimuli may be         priced differently from a promotion that does not use touch         stimuli. A promotion that uses smell may be priced differently         from a promotion that does not use smell. -   10. Criteria. The advertiser has certain types of criteria for what     type of ad space they want. Do they want a picture, a video? Do they     want high resolution or low resolution? Check on the available     content. Does the available content match the criteria for an ad? So     there is a process of discerning what type of ad space an advertiser     wants and matching the ad space to the available content.     Advertisers may prefer video, still image, audio, and/or any other     specific format for a promotion. Accordingly, advertisers may filter     out slot purchases and/or ad campaign purchases by the type of     device through which the promotion will be run so that only devices     that are suited for the type of promotion are used. For example, if     an audio only promotion is desired, an advertiser may not want to     purchase a campaign that includes a slot on a video monitor.     Accordingly, campaigns may be paired only with devices that match     the promotion media and/or advertisers may select devices by     filtering out those that are designed for certain media but not     other media.     -   10.1. Feedback/review process. The advertiser gets to see what         his ad will look like when actually shown. In some embodiments,         when an advertiser submits information about a promotion, the         advertiser may be given the opportunity to see an example of how         the promotion will look and/or sound. The example may include a         simulation of an image and or video displayed through a mobile         gaming device, on a monitor, on a ticker, on a kiosk, and so on.         The simulation may be presented through a computer interface         (e.g., a web interface, a flash interface, and so on). The         simulation may include elements form a simulated casino with the         promotion in effect (e.g., slot machines, tables and so on). In         some embodiments, audio may be played to simulate the promotion.         In some embodiments, advertisers may be able to move through a         simulated 3d environment to see and hear how a promotion may be         perceived at different locations within an environment.     -   10.2. A debugger for an active dynamic campaign. In some         embodiments, an advertising campaign may include a plurality of         different triggers for display of a promotion, rules for         determining what types of devices to display a promotion on, and         a casino or other public space may be filled with a plurality of         people engaging in a plurality of activities, so that the         execution of a promotion over the activities may result in a         complex number of rules being triggered and displays and sounds         be made that change nearly continuously. It may be beneficial to         an advertiser or administrator of an advertising system to be         able to simulate an advertising campaign being executed in a         public space with a simulated set of people moving interacting         in the simulated space in order to debug or otherwise appreciate         how the campaign might be executed. A simulation may include a         plurality of simulated people in a simulated public space. The         simulated people may have simulated demographics, engage in         simulated activities, engage in simulated games, and so on. The         simulation may include simulated devices that correspond to real         devices on which a promotion may be made (e.g., simulated mobile         gaming devices held by simulated people, simulated monitors         positioned where a real device might be positioned in a real         environment, simulated slot machines, and so on). The simulation         may display what devices are being used for what portion of a         promotion and why in some implementations. The simulation may         display rules or triggers being fired (e.g., a person wins and         is shown an ad) and/or other characteristics being used to         determine how the promotion would be made if the simulated         people were real people. -   11. Data about players that is available for reference. In various     embodiments, a casino may store various data related to a player.     Data may be received in various ways. A player may provide data     about himself to the casino. For example, a player may provide data     when making a reservation or when signing up for a player tracking     card. The casino may receive data about a player when performing a     check on the player, such as when performing a check, on a player     prior to granting credit to the player. The casino may receive data     about a player by tracking its interaction with a player. For     example, through the player's interaction with the casino, the     casino may gather data about a player's wins and losses, recent     outcomes, and so on.     -   In various embodiments, data about a player may be used by         marketers to select a target audience for their promotions. For         example, a marketer may decide that he wishes to advertise only         to players with high skill levels at video poker. In various         embodiments, a marketer may select a target audience by         navigating through a series of menus. One menu may relate to         age. Using the menu, a marketer may select an age range for his         target audience. Another menu may relate to income. Using the         menu, the marketer may select an income range for his target         audience.     -   In various embodiments, having selected a target audience, a         marketer may indicate that he wishes his promotions to go to the         target audience. In various embodiments, having indicated a         target audience, the marketer may first view statistics         describing how many of his target audience are currently         available for viewing promotions. For example, the marketer may         view statistics describing how many of his target audience are         currently using mobile gaming devices. If the marketer is         satisfied with the number of his target audience that are         available, then the marketer may indicate he wishes his         promotion(s) shown to the target audience.     -   In various embodiments, one or more of the following types of         data may be available with respect to a player: (a) name; (b)         address; (c) gender; (d) date of birth; (e) data derived from         games the player has played; (f) a skill level of the player at         a game; (g) a skill level of the player at Blackjack; (h) a         skill level of the player at video poker; (i) transaction data         for the player; (j) an average deposit size for the player; (k)         a bet amount made by the player; (l) an average bet amount made         by the player; (m) a bet limit for the player (e.g., a maximum         amount that a player is allowed to bet per game; e.g., a maximum         total that a player is allowed to bet over a plurality of games,         such as over a session of games); (n) a bet limit for the player         that has been self-imposed by the player (e.g., a maximum amount         that a player is allowed to bet per game by request of the         player); (o) a loss limit for the player (e.g., a maximum amount         that a player is allowed to lose over some period of time,         beyond which the player will be prevented from further         gaming); (p) a deposit limit for the player (e.g., a maximum         amount that a player is allowed to deposit in a gaming machine;         e.g., a maximum amount of chips that a player is allowed to buy         at a gaming table).     -   In various embodiments, one or more of the following types of         data may be available with respect to a player: (a) residential         address; (b) residential address city; (c) residential address         country; (d) residential address preferred; (e) residential         address street; (f) residential address suburb; (g) residential         address zip; (h) postal address; (i) postal address city; (j)         postal address country; (k) postal address preferred; (l) postal         address street; (m) postal address suburb; (n) postal address         zip; (o) contact details; (p) email; (q) secondary email; (r)         fax number; (s) mobile (e.g., the phone number for the player's         mobile device); (t) pager (e.g., the contact number for the         players' pager); (u) preferred contact method; (v) business         number (e.g., the phone number for the player's business); (w)         home number (e.g., the phone number for the player's home); (x)         credit cards details; (y) personal details; (z) agent code; (aa)         date of birth; (bb) first name; (cc) last name; (dd) middle         name; (ee) national id; (ff) nationality (e.g., the player's         country of origin; e.g., the country in which the player has         citizenship); (gg) promotional code; (hh) sex; (ii) title; (jj)         authentication question and answers (e.g., questions about the         player's mother's maiden name and answers to such questions);         (kk) bank account details; (ll) bank name; (mm) bank_account_id;         (nn) branch_address; (oo) branch_code; (pp) branch_country; (qq)         account_name; and (rr) account_no. -   12. Screening. Make sure there are no inappropriate promotions,     promotions which violate copyrights, etc. In some embodiments,     advertisers may submit promotions through a portal or otherwise.     Before those promotions are shown or otherwise transmitted to users     of a mobile gaming device, a processes of verifying that the     promotions adhere to a set of standards may be performed. The     process, for example, may search for vulgar, pornographic, indecent,     copyright infringing, or otherwise unwanted material. The process     may include human actions, computerized actions and/or other     actions. For example, a computer algorithm may search for certain     offensive words in a promotion, search for a color hue that     corresponds to human flesh colors, and so on. If such offensive     material is found, the promotion may be rejected, the promotion may     be sent for review by a human, and so on.     -   12.1. All promotions inspected by casino employees. In some         implementations, all promotion may be inspected for offensive         material by a casino employee or other person before the         promotions are run. If offensive material is found, the         promotion may be rejected, the advertiser may be notified to         correct the promotion, the employee may work with the advertiser         to remove the material, the material may be censored and the         promotion may run without the material, and so on.     -   12.2. Advertisers sign term sheets detailing the limitations a         promotions. In some embodiments, an advertiser may be asked to         sign a release or terms of service agreement before a promotion         is run. The agreement may include limitations about materials         that may be included in the promotion. Such limitations may vary         from location to location within a casino (e.g., bars areas may         allow some material that is not allowed in restaurants), from         time to time for when the promotion is to run (e.g., some         material may be allowed later in the night that is not allowed         during the day), and so on.         -   12.2.1. Penalties for violation In some embodiments, if an             advertiser violates the agreement, a penalty may be             assessed. The penalty may include removal of the promotion,             a fine, censorship of the material, banishment from the             advertising service, decreased priority for running             promotions, increased fees in the future, removal from             certain devices, and any so on.     -   12.3. Wait period between when promotions are submitted and when         they are approved. In some embodiments, after an advertiser         submits material for a promotion, there may be a waiting period         before that material may be used. The waiting period may be used         to verify that no offensive material is included in the         promotion. Accordingly, in a bidding process for a slot,         advertisers may submit material for approval before the end         point of the bidding process if the end point is near the time         of the slot so that there is little or no delay and the slot may         be utilized for the promotion. The wait period may be any amount         of time that may be used to verify a promotion (e.g., one day,         one hour, one minute). The waiting period may be a minimum time,         an actual time needed, a standard time, a random time, and so         on. -   13. Allocation. Who do we present the advertisements to? How do we     allocate ads to the people viewing the ads? In some embodiments,     promotions may be presented to users of mobile gaming devices.     Promotions may also be presented to users of stationary gaming     devices that carry mobile gaming devices, or other mobile devices     that allow tracking (e.g., cell phones, PDAs, etc.) with them.     -   13.1. The ads can be based on the player. Promotions shown on a         mobile gaming device or on another device may based on         information about a single player or on information about a         plurality of players. For example, a promotion for Coke may be         shown to a player that has a known affinity to caffeinated         sugary beverages. Such a promotion may be shown on a mobile         gaming device directly to the player. As another example, if a         group of people with the same affinity are in an area, the         promotion for Coke may be shown to all of them through another         device, such as a monitor facing the group of people.         -   13.1.1. The ads can be based on the demographic of the             player. In some embodiments, the promotions shown to the             player or players may be based on demographic information             about he player or players. For example, some promotions may             be targeted to specific genders, ages, incomes, etc. Those             promotions may be shown to players that match some or all of             those criteria.     -   13.2. The ads can be selective to certain locations in the         world. In other words, the ads can be put only in certain         locations without trying to figure out necessarily who goes         there or not. In some embodiments, promotions may be placed in a         specific area of a world (e.g., a casino floor or a virtual         gaming world). The promotion may be placed there so that any         person passing may view the promotion.     -   13.3. The ads are based on how a game proceeds. An ad might come         up only on a winning hand. The ad can come up if the game is         simply likely to turn out a certain way (e.g., if the game is         likely to be a winning game) even if the game hasn't finished         yet. In some embodiments, the progress of a game being played on         a mobile gaming device may be monitored and that information may         be used to direct promotions. In some embodiments, the progress         of a live game may be monitored (e.g., by cameras, casino         personnel, etc.) and that information may be used to direct         promotions. Events related to a game may be used to influence         what promotions are shown to a player or players. For example, a         win in a game, a loss in a game, a win of a threshold amount         over one or more games, a loss of a threshold amount over one or         more games, a jackpot win, a particular hand in a card game         (e.g., black jack, royal flush, etc.), a chance of winning above         a threshold (e.g., a player is 70% likely to win the ongoing         game of blackjack), a particular card or symbol is played, and         any other events may trigger a promotion being shown to a player         or group of players. In some implementations, for example, good         events or wins may trigger promotions for spending money or         celebration, bad events or losses may trigger events for saving         money or free play.     -   13.4. A factor determining whether or which ad is played could         be a player's balance. If the balance increases over some period         of time, an ad can be shown. In some embodiments, a player's         balance of money may be a used to determine which promotions to         show the player. For example, if a player wins over time,         opportunities to spend the winnings may be shown. If a player         loses over time, opportunities to save money may be shown. Some         promotions may be shown only to players with balance over a         threshold amount. Such balance limitation may prevent promotions         for expensive luxury items from being shown to players that         could not afford those items.     -   13.5. Ads shown could correlate with the size of a progressive         jackpot. In some embodiments, a size of a progressive jackpot         may influence the promotions shown to players. The size may         influence, for example, promotions shown to people playing a         game related to the progressive jackpot, to players near a game         device that is related to the progressive jackpot, to players         that are choosing which game to play, and so on. As a jackpot         increases, promotions for more expensive and luxurious things         may be shown. Such promotions may have the effect of both         incentivizing players to play the game and to buy the item if         they win the jackpot.     -   13.6. A factor determining which ads are shown on the mobile         device is the location of the mobile device. In some         embodiments, promotions may be shown based on a location of a         mobile gaming device and/or player. For example, some promotions         may be shown in a particular casino or based on a player's         location within a casino. Each casino may have its own ad server         from which promotions are transmitted to devices. Ads may be         distributed from the central service to the ad servers at the         casino based e.g., on which casino the promotion is targeted to. -   14. Downloading advertisements to the mobile device. It should be     recognized that material related to a promotion may be stored on a     mobile device and/or transmitted to a mobile device in any way.     -   14.1. Downloading ads when the mobile device is docked (e.g.,         for charging, e.g., for playing on the large screen). In some         embodiments, material (e.g., images, sound, video, etc.) related         to one or more promotions may be transferred to and/or stored on         a mobile gaming device when the mobile gaming device is docked         for charging. In some implementations, the mobile gaming device         may dock to a power and data transfer station that allows         recharging and transferring of data to and/or from the mobile         gaming device. A set of information about promotions that may be         used to display promotions for a period of time may be stored on         the mobile gaming device (e.g., transferred from a central         server) when the mobile gaming device docks. Accordingly, when         promotions are to be displayed, the data may already be stored         on the mobile gaming device. The docking may be performed, for         example, by a casino employee between uses by a customer, by a         customer between gaming sessions (e.g., at a docking station in         a hotel room), and so on.     -   14.2. Downloading on the fly (e.g., downloading wirelessly). In         some embodiments, material (e.g., images, sound, video, etc.)         related to one or more promotions may be transferred to and/or         stored on a mobile gaming device when the promotion is to be         displayed (e.g., streaming) or when it is determined that the         promotion is to be displayed soon. Such transferring of material         may take place wirelessly over a communication network         connecting the mobile gaming device to a content server.     -   14.3. Having a casino rep deliver a memory stick with more         advertisements on it. In some embodiments, material (e.g.,         images, sound, video, etc.) related to one or more promotions         may be transferred to and/or stored on a mobile gaming device by         a physical connection to a memory device (e.g., card, stick,         etc.). The memory device may be connected and/or delivered to         the device by a casino employee. -   15. Report to advertisers after their ad has been shown In some     embodiments, a report regarding promotions shown to players may be     given to advertisers. The report may identify which promotions were     shown to which players, why the promotions were shown, an     effectiveness of the promotions, a charge for the promotions, and     any other information to information the advertisers about the     promotion. The report may provide advertisers with detailed     information regarding promotions, for how much money, to whom, in     which games, when, & in what context (possibly storing screen shots     or data that permits the screen image to be recreated). In some     implementations this information may be captured by a central server     that feeds promotion material to devices. In other implementations,     the mobile device may be operating independently of the central     server at times. The mobile device may record what promotions have     been shown and later report those to the central server.     -   In various embodiments, a mobile gaming device may inform the         casino server when a promotion has been presented. For example,         the mobile gaming device may inform the casino server of date         and time when a promotion was presented. The mobile gaming         device may further provide an identifier for the promotion. The         casino server may then bill the marketer who sent the promotion         for the presentation of the promotion. In various embodiments, a         mobile gaming device may transmit one or more of the following         pieces of information to the casino server: (a) the date of a         promotion's presentation; (b) the time of a promotion's         presentation; (c) an indication of which promotion was presented         (e.g., an identifier for a promotion; e.g., “The Ford         Promotion”); (d) a format in which a promotion was presented         (e.g., a promotion was presented only as a still image; e.g., a         promotion was presented in its abbreviated 3 second form; e.g.,         a promotion was presented in its full 20 second form; e.g., a         promotion was presented as audio only); (e) a sponsor of a         promotion; (f) a length of a promotion; (g) a game during which         a promotion was presented; (h) a location on a display screen         where a promotion was presented; (i) one or more outcomes which         occurred on the player's mobile gaming device preceding the         promotion (e.g., a promotion may cost a marketer more if the         promotion was made following a string of winning outcomes for         the player); (j) a player's reaction to a promotion (e.g., the         player wished to find out more information; e.g., the player was         bored with the promotion); (k) and any other pertinent         information.     -   In various embodiments, the casino server may include accounting         software. The software may track when promotions have been         presented, how much is owed to the casino based on such         presentations, how many remaining presentations of a promotion         must be made, how much has already been paid by a marketer, who         a promotion has been presented to, and any other information         related to a promotion, amounts     -   In various embodiments, a mobile gaming device may verify with         the casino server that a promotion should be presented before         actually presenting the promotion. For example, the mobile         gaming device may send an identifier associated with the         promotion to the casino server. The casino server may check a         record of promotions that had been transmitted to the mobile         gaming device. If the record does not contain the identifier         transmitted to the casino server by the mobile gaming device,         then the casino server may instruct the mobile gaming device not         to present the promotion that the mobile gaming device had         indicated. -   16. What rewards can advertisers give? In some embodiments,     advertisers may provide players with rewards for viewing promotions,     and/or taking some action related to the promotions. For example, an     advertiser may provide a reward for viewing a sales pitch related to     a product, for purchasing a product, for clicking on a sponsored     link, and so on. The rewards may include rewards that change game     play, sponsored game play, physical objects, and so on.     -   16.1. Free symbols, such as wild cards. In some embodiments, an         advertiser may reward a player by changing a game to include a         new symbol (e.g., a new card, a new slot symbol, and so on). The         new symbol may have beneficial properties that increase payouts         or increase winning odds, for example. In some implementations,         the new symbols may include wild cards or wild symbols.     -   16.2. Extra pay-lines. In some embodiments, an advertiser may         reward a player by sponsoring or otherwise adding pay-lines to a         slot machine or hands to a card game. The added pay-lines may         act similar to normal pay-lines and/or have different rules or         payouts.     -   16.3. Moving your bet to a higher category (e.g., a 50-cent bet         becomes a 75-cent bet). In some embodiments, an advertiser may         reward a player by increasing a bet made by the player and/or         increasing a bet to a higher category of bets that might not be         available for an amount bet normally. For example, a 50 cent bet         may qualify for a first set of odds, and a 75 cent bet may         qualify for second set of odds. The advertiser may reward a         player by increasing the odds of a 50 cent bet to those of a 75         cent bet and/or by providing a supplemental 25 cents for such a         bet.     -   16.4. Free moves of a game piece. In some embodiments an         advertiser may reward a player by allowing the player to make a         move in a game that would not normally be allowed. For example,         a free move of a game piece that would normally require a         payment or a waiting period may be provided.     -   16.5. Give a better pay table (e.g., double jackpot payout,         higher payout percentage on slot machine). In some embodiments,         an advertiser may reward a player by improving terms of a game.         For example, the advertiser may increase odds or increase         payouts of a game.     -   16.6. Give a do over/mulligan (e.g., replace the last card drawn         with a new draw). In some embodiments, an advertiser may reward         a player by allowing a player to replay a game or a portion of a         game. The replay may include replaying with new game elements         (e.g., new cards in a deck) or replaying with the same game         elements. For example, a player may be able to replay an action         in a blackjack game that caused the player to bust. The player         may, for example be offered the option to receive a new card         and/or may be offered the option to take back the hit and choose         to stand.     -   16.7. Give advice on game play (e.g., “you should stand now”).         In some embodiments, an advertiser may reward a player by         offering the player advice on a game. The advice may include         advising the player how to play according to a desirable         strategy (e.g., basic strategy). The advice may be based on         knowledge that players do not have (e.g., knowledge of odds,         knowledge of upcoming cards in a deck, and so on).     -   16.8. Rewards particular to a mobile device. In some         embodiments, a reward may include customization or other addons         to a mobile device such as a cell phone or mobile gaming device.         The customization or addons may relate to the promotion (e.g.,         games branded with the promotion, etc.). In some embodiments, a         reward may include a free ring tone, software (e.g., games,         applications), free cell phone minutes, free music downloads,         free video downloads, and so on. -   17. Public Service Games/Announcements. In some embodiments, a     device may offer a public service related game and/or display public     service announcements similar to the display of promotions. Rather     than advertisers, public organizations, such as police, the FBI, and     so on may submit material to be used for such announcements.     -   17.1. An “America's Most Wanted Slot Machine.” Real and current         criminals may be used in a slot machine game or card game.         Missing children or other people can be put on the reels of slot         machines or card games in other implementations. If a player         recognizes one, the player can contact the FBI (perhaps through         the slot machine, or perhaps through a separate channel). The         slot machine thereby provides a public service. The criminals         can be tailored to the locality. For example, people who are         wanted criminals in Tennessee can be put on the reels of slot         machines located in Tennessee. A player may be given a reward or         bonus if the player helps to capture a criminal or find a         missing person.     -   17.2. The gaming network could disseminate useful information         Information from civilian broadcasts (e.g., about disaster         alert, etc., weather, news items, casino images from a web cam,         and any other information may be distributed similar to         promotions discussed above. -   18. Regulatory approval of advertisements. Game modifications     typically require approval by the regulators. In some embodiments,     each promotion may be separately approved by regulators for     inclusion in a game. In other embodiments, games may be designed so     that some or all promotions are run separately from the running of a     game (e.g., by a separate processor, by a separate processing     thread, and so on). Accordingly, regulatory approval of each new     promotion added may not need regulatory approval. In some     embodiments, promotional material may be preapproved for inclusion     in certain spots in a game or certain spots in a game may be     approved for use in promotions that meet certain criteria.     -   In various embodiments, a casino may seek regulatory approval to         feature or insert a promotion into a game. In various         embodiments, a casino may seek regulatory approval to feature or         insert a graphic associated with a promotion into a game. In         various embodiments, a casino may seek regulatory approval to         feature or insert any graphic into a game. The game may be a         game of chance played for money, such as a slot machine game or         video poker game.     -   In various embodiments, a casino may receive blanket approval to         insert any one of several graphics, at the casino's discretion,         into a game. For example, the casino may desire regulatory         approval to insert any one of 50 different graphics into a game.         For example, the casino may desire regulatory approval to insert         any one of 50 graphics as a symbol into a game. The graphics, or         any data related to a promotion, may be shown in advance to         regulators. The regulators may approve all the graphics, or         other data, and may then allow the casino to insert any one of         such graphics, at its discretion, into the game. Terms of         regulator approval for inserting a graphic into a game may         include any one or more of the following: (a) the presence of a         graphic has no effect on the game when compared to how the game         would be played if the graphic were not present; (b) the         presence of a graphic has no effect on the payout of the game         when compared to what the payout of the game would be if the         graphic were not present; (c) the graphic in no way indicates or         represents something that is not true (e.g., a graphic cannot         say “winner” if the graphic does not form part of a winning         outcome); (d) the graphic in no way indicates or represents         anything about the game itself (e.g., the graphic does not         suggest an amount of a payout, a winning or losing outcome, an         entry into a bonus round, etc. The graphic may simply convey a         message that is independent of the game play); (e) the graphic         is not offensive; (f) the graphic cannot be confused for another         graphic that is already part of the game; (g) the graphic cannot         be confused for a graphic that is part of any game (e.g., a         graphic of a clown might be forbidden because it might be         confused with a joker symbol); (h) the graphic may not appeal to         children or minors (e.g., the graphic may not show toys or         brands which appeal to children); and so on. It will be         appreciated that the foregoing terms may apply to video,         cartoons, animation, audio, or any other information which may         be featured in a promotion.     -   Obtaining regulatory approval on the foregoing may allow a         casino to solicit promotions which may be obtained from         marketers and then which may incorporated into games. A new         promotion may be received and then incorporated without the         necessity of obtaining regulatory approval between the time the         promotion is received and the time the promotion is         incorporated. This may allow for marketers to enjoy a rapid         turnaround time between when promotions are submitted and when         the promotions are incorporated. -   19. Ads appear on the mobile gaming device (or music player) and     disable all other functionality. In some embodiments gaming or menu     components may disappear or be disabled when a promotion is     displayed. The user may be forced to click on the promotion in order     to continue doing what he had been doing or wants to do. For     example, the user must click on the promotion to play games or to     access a menu where he can select music to listen to. The user may     thereby have his games sponsored by the advertiser. In turn, the     advertiser pays according to the number of clicks. For example, the     advertiser pays a fixed rate for 100 clicks, showing that the ad has     been viewed 100 times. -   20. Choosing among multiple promotions to show. In some embodiments,     if multiple promotions may be shown, the one that shows a particular     product may be favored if that product's sponsor has paid more for     the privilege. In some implementations, the proportion of times a     promotion is shown may be related to the amount paid for the     promotion related to the amount other advertisers paid for their     promotions. For example, a slot machine may determine that a player     should win 10 coins. There may be two promotions that one could show     the player. One would include two “Ford” symbols. Another would     include two generic symbols, such as two “cherry” symbols. The more     Ford has paid, the more the former outcome might be shown. In other     words, the company that has paid more may have their symbols shown     more often. -   21. Only display ads in the slot machine when there is a win. In     some embodiments, promotions may only be shown in a game after a     win. Limiting such promotions to a win may provide good will to the     advertisers associated with the promotions similar to a sponsorship     of the win. -   22. Non-competition among promotions. In some embodiments, when one     advertiser has a sponsored outcome in a game (e.g., a Ford slot     symbol) that wins X for a player, the company may require or a     central server may ensure that no competitor has another outcome     that wins more than X for the player. For example, Toyota in the     above example may not be allowed to have a higher winning outcome     because that may make the Ford look bad. In some embodiments, a     determination of whether two advertisers are competitors may be     made. The determination may be made based on information submitted     by the advertisers (e.g., indications of competitors). In some     embodiments, if two advertisers are competitors only one promotion     may be shown, but if they are not competitors both promotions may be     shown. -   23. Incentives based on where you are in the casino, particularly in     relation to where you are in relation to the gaming zone. In some     embodiments, promotions may be based on location of a mobile gaming     device within a casino. The location may include proximity to a     vendor, as discussed above. The location may also include location     with respect to the gaming area. The promotions may be targeted to     keep a player within a gaming area.     -   23.1. Types of incentives Promotions may include incentives to         play more games, such as sponsored play, new game types, rewards         from advertisers, as discussed above, and so on. Promotions may         include incentives to stay in an area (e.g., to talk to a         representative for a product you should stay where you are) to         walk through an area (e.g., go talk to a representative in the         middle of the gaming area or on the other side of the gaming         area, go to a store on the other side of the gaming area or away         from the cage, etc.).     -   23.2. Critical areas of the casino Promotions may be directed to         move players away from certain area or keep players in certain         areas of a casino.         -   23.2.1. The cage Players visit the cage to exchange chips or             other winnings for cash. As a player moves towards the cage,             promotions may be presented that incentive the player to             move away from the cage and/or continue gaming         -   23.2.2. Edge of gaming zone. To leave a gaming area, players             must cross over an edge of the gaming area. As a player             moves to the edge of a gaming area, promotions that             incentivize the player to stay within the gaming area, move             away from the edge of the gaming area, and/or continue             gaming may be shown to the player. -   24. Tracking the player's path. In some embodiments, a player's     players path may be tracked and or estimated. Promotions may be     presented based on a path (e.g., along a path, in order to alter a     path).     -   24.1. Obtaining the path data. Path data may be determined from         a change of a location of a mobile gaming device within a         casino. Path data may be estimated by extrapolating a past path         in a continuous direction, by analyzing historic path data of         people that have taken a current path of a player, and so on.     -   24.2. Correlating path data with other data. Path data may         correlate with other actions or preferences of a player. For         example, a player that moves towards a bar may likely desire a         drink, a player that moves towards a casino cage may want to         stop gambling, and so on. Such information may be used to direct         promotions to the player.         -   24.2.1. Put path data together with gaming data. E.g., has             person stopped gaming for the last five minutes, and now is             up and walking? In some embodiments, gaming activity and or             any other activity may be combined with path data to             determine what promotions to direct to a player. If a player             stops gambling after a period of gambling, for example, and             walks towards an edge of a gaming area, promotions to keep             the player in the gaming area and continue gaming may be             presented to the player. If a player wins a big win and             heads towards a shopping area, promotions for large luxury             items may be presented to the player.     -   24.3. Correlation in paths of separate people. Conclude they are         together. In some embodiments, a correlation in behavior among         multiple players may be determined (e.g., players walk together,         players arrive together, players sit at a table together,         players play a same game, they are at a plurality of same         locations, and so on). If player behavior correlates to a         threshold extent (e.g., they stay together for 10 minutes at a         bar, they play more than one game together, they walk around a         casino together, etc.) the players may be deemed to be part of a         party. Promotions maybe directed to correlated players in a         coordinated fashion (e.g., similar promotions may be shown,         complimentary promotions may be shown, preferences of one player         may be attributed to another player, and so on). In some         embodiments a promotion related to a first player may be shown         to a second player if the two players are determined to be         related.         -   24.3.1. Build Relationship profiles based on correlations             and other information. In some embodiments, the amount and             type of correlation between activities and paths of people             may be used to develop profiles about he relationships of             those people. For example, if genders are known, we may be             able to estimate if two people are friends hanging out for a             night or a couple out for a date, etc. If two people are             staying in a hotel room, we may know the type of room and             number of rooms (e.g., one bed or two, one room or two) and             may use that to determine a relationship type (e.g., one bed             indicates a romantic relationship, two rooms indicates             friends). Also, a social network may be developed. For             example, if A and B correlate, Then B and C correlate. We             may determine that there is some link between A and C. Such             a link and information may be developed over multiple visits             by multiple people and may be used at any date to direct             promotions. So, for example, person A and B may enjoy one             type of entertainment and gaming one night, so that when             person A and C arrive together, similar preferences may be             attributed to person C.         -   24.3.2. Relative movement as trigger for promotions In some             embodiments, if two players are determined to be related in             some way, a relative movement of the two players may be used             to trigger promotions. For example, if two players move             closer together (e.g., based on the location of mobile             gaming device used by the players) a promotion related to a             group activity may be shown. As another example, if two             players move farther apart, a promotion related to             individual activities may be shown.     -   24.4. Feedback to player based on his path. In some embodiments,         feedback may be provided to a player to put a player on a path         associated with a promotion. For example, directions to get to         an area related to a promotion may be provided, audio feedback         may be provided telling a player if they are moving in the right         direction, visual data displaying arrows or other images         indicating a direction may be provided, and so on.     -   24.5. Estimating a path In some embodiments, a location of a         mobile device may be determined. A change in the location may be         determined. In some embodiments, a path along which a player         using the mobile device is likely to travel along may be         determined based on the location and the change in location. The         path may be an estimate of a path along which the player is         likely to travel in a predetermined period of time (e.g., within         the next minute, etc.). The path may be determined based on data         collected about the player's prior movements and/or data         collected about other players' prior movements. Historically         collected data may be used, for example, to determine that         players starting in a first location that make a move in a first         direction typically travel along the path. In some         implementations, demographic information may be used to more         accurately predict the path by limiting the sample of historic         paths to paths taken by players similar to the player.         -   24.5.1. Activating promotions along an estimated path In             some embodiments, promotions may be shown along an estimated             path (e.g., on one or more devices along the path). In some             embodiments, devices may be selected for showing a promotion             based on a direction the device faces. For example, a device             may be selected if the device faces along the path in the             direct of the player.     -   24.6. Putting physical ads, people, or other items along an         anticipated or well-traveled path. In some embodiments,         collected information about paths taken by players may be used         to determine typical paths taken by different players at         different times. Promotions may be placed along those paths in         anticipation of similar paths being used by similar people in         the future. For example, a path around a card game area may be         determined to be traveled by people between the age of 25 and 40         between 5 and 9 frequently, so promotions targeted at that         demographic group may e placed along the path.         -   24.6.1. Block off a path that typically means a player will             stop playing. In some embodiments, a correlation may be             determined between a path traveled and a player not gambling             anymore. In some implementations, such information may be             used to adjust paths so that the particular path is blocked             off or adjusted to direct players to a different path (e.g.,             one not correlated with an end of gaming) -   25. The player chooses a type of ad at the time when he checks out a     mobile device. In various embodiments, a player may make one or more     designations at the time when he receives a mobile device. Such     designations may influence the promotions and advertisements shown     to the player. For example, such designations may influence the     types of companies that advertise to the player or the types of     products that are advertised to the player.     -   A player may receive a mobile device in a number of ways. In         various embodiments, a player may receive a mobile device at a         cage at a casino, at a vending machine, or at a front desk at a         casino hotel. In various embodiments, a player may receive a         mobile device from a casino representative. For example, a         player may be situated at a slot machine and wish to move around         the casino while continuing to engage in gaming. Accordingly,         the player may request that a casino representative provide the         player with mobile device for gaming. A player may also be in         possession of a mobile device of his own (e.g., the player may         be in possession of a personal cell phone). A player already in         possession of a mobile device may make one or more designations         pertaining to advertisements at the time he configures or         enables his mobile device for the purposes of gaming.     -   When receiving or configuring a mobile device, a player may make         a number of designations. The player may indicate: (a) a product         (e.g., Coke); (b) a category of products (e.g., soft drinks;         e.g., leisure cruises); (c) a brand; (d) a company; (e) a         manufacturer; (f) a purpose for a product (e.g., as a wedding         present; e.g., something to clean a bathroom); (g) a price range         (e.g., a price range for a product that the player may be         willing to buy; (h) a budget range (e.g., an amount the player         may have available to spend); (i) a desired sales representative         or type of sales representative that the player may be         interested in communicating with (e.g., a life insurance agent).         Such designations by the player may allow a marketer to         determine the desirability of sending advertisements or         promotions to a player. For example, if a player has designated         the product category of a particular marketer, then the marketer         may be more willing to pay to have the player view an         advertisement for the marketer's product. The designations may         also aid the casino in selling advertising space to marketers.         For example, the casino may be able to convince cruise lines to         advertise on the mobile devices of players if the casino can         show cruise line marketers that a number of such players are         interested in vacations on cruise lines.     -   When receiving or configuring a mobile device, a player may also         indicate characteristics about himself/herself. The player may         indicate an age, race, income level, place of residence, family         status, gender, political preference, occupation, or any other         piece of information. Such information may further aid marketers         in deciding which players to advertise to, how much to pay to         provide advertisements, and in deciding what advertisements to         send to one or more players. -   26. Bonus round on a separate device In various embodiments, a     player may engage in part of a game on a mobile gaming device, and     part of the same game on another device. The other device may be a     gaming device that is not a mobile device. For example, the other     device may be a slot machine, video poker machine, video blackjack     machine, or the like. In some embodiments, the gaming device may     offer an experience to the player that is not available on the     mobile gaming device. Thus, it may be more exciting or otherwise     pleasing for the player to play a portion of a game on the other     gaming device rather than playing the entire game on the mobile     gaming device. In some embodiments, a player may reach a bonus round     of a game while playing on a mobile gaming device. The bonus round     of the game may feature random event embodied in a physical process.     For example, the bonus round may feature the spinning of a wheel.     While it is possible that the spinning of a wheel may be visually     simulated using a display screen of a mobile gaming device, for     example, it may be more exciting for a player if he actually sees a     physical wheel spin. Thus, a player may play out the bonus round     portion of his game using a gaming device that is not mobile. The     gaming device used for the bonus round may include a physical     spinning wheel. The wheel may spin to reveal the player's prize in     the bonus round.     -   In various embodiments, when a first portion of a game is played         on a mobile gaming device, and a second portion of a game is         played on another device, the outcome of the game may be         determined in several ways. The outcome of the game may be         determined solely based on random numbers or events generated by         the mobile gaming device. The outcome of the game may be         determined solely based on random numbers or events generated by         the other device (e.g., by a gaming device that is not mobile).         The outcome of the game may be determined solely by a third         device, such as by a casino server. The outcome of the game may         be determined based on random numbers or events generated by         both the mobile gaming device and the other device (e.g., the         gaming device that is not mobile). For example, entry into a         bonus round may be determined based on random numbers generated         on a mobile gaming device. The outcome of the bonus round may be         based on random numbers generated at the other device (e.g., at         the gaming device that is not mobile). The outcome of the game         may be determined based on random numbers or events generated at         the mobile gaming device and at the third device (e.g., the         casino server). The outcome of the game may be determined based         on random numbers or events generated at the other device (e.g.,         at the gaming device that is not mobile) and at the third device         (e.g., at the casino server). The outcome of the game may be         determined based on random numbers or events generated at the         mobile gaming device, at the other device (e.g., at the gaming         device that is not mobile), and at the third device (e.g., at         the casino server). -   27. 100% Payback device In various embodiments, a game on a mobile     gaming device may have a house edge of 0%. In various embodiments, a     game on a mobile gaming device may have a negative house edge. As     will be appreciated, games with 0% house edge may fail to yield     profits for a casino. As will be appreciated, games with a negative     house edge may potentially cost a casino money. Thus, in various     embodiments, a casino may use revenue from presenting promotions in     order to supplement costs associated with games that have 0% or less     house edge.     -   In various embodiments, a casino may present enough promotions         on a mobile gaming device to create a desired positive house         edge when earnings from promotions are counted. For example, for         each 1 game played on a mobile gaming device, the mobile gaming         device may present 5 promotions. For example, the five         promotions may include five products which take the place of         symbols on simulated slot machine reels. For each promotion         presented, the marketer sponsoring the promotion may pay the         casino one cent. Thus, the casino may earn five cents from         marketers for each 1 game played. Even if the house edge on the         game itself is 0%, the casino may effectively maintain a 5%         house edge when earnings from promotions are taken into account.         In order to attain a desired effective house edge, a casino may         adjust the number of promotions presented per game played and/or         adjust the fees charged to marketers per promotion. For         instance, in the foregoing example, if the casino wished to         receive a 6% house edge, the casino may have caused the         presentation of 6 promotions per game rather than 5.     -   In various embodiments, a player of a game may be required to         view or otherwise peruse one or more promotions in order play         games with a zero or negative house edge. As a player views         promotions, a player may accumulate points, tokens, or other         scrip. The player may be required to accumulate a certain number         of points in order to play games with a zero or negative house         edge. As the player approaches a target number of points, the         house edge may get smaller and smaller, reaching zero when the         player achieves the target number of points. For example, a game         may conventionally have a house edge of 10%. However, when a         player has viewed half of the promotions required to play games         with a 0% house edge, the house edge may decline to 5%. In         various embodiments, as a player accumulates points, the player         may use such points to play a game with a 0% or negative house         edge. Once the player uses up points, the player may be required         to earn further points (e.g., by viewing more promotions) in         order to play further game with a 0% or negative house edge.     -   In various embodiments, a meter or other gauge may indicate a         player's progress towards being able to play games with a 0%         house edge. As a player views more promotions, for example, the         meter may more closely approach a target. When the target is         reached, the player may be able to play games with a 0% house         edge. In various embodiments, a player may be required to         continually, periodically, or sporadically view additional         promotions in order to maintain the privilege of playing games         with a 0% or negative house edge. If the player fails to view         promotions at the desired rate, the player may lose points         and/or the meter may move away from its target range. The player         may then be left to play games with a positive house edge until         such time as the player views additional promotions. -   28. Providing Information and Encouraging Other Activity In various     embodiments, a mobile gaming device may display a promotion that     serves to encourage a player to play at a stationary gaming device.     For example, a player may be holding a mobile gaming device as he     walks through a casino. The mobile gaming device may start buzzing     and then display a message. The message may inform the player that a     stationary gaming device of a certain type is nearby. For example,     the message may read, “There is a great game called Jackpot Jungle”     to your right. It is very lucky today!”. In various embodiments, a     mobile gaming device may detect the presence of a nearby stationary     device, or vice versa. The mobile gaming device may then encourage     the player to visit the nearby stationary gaming device. There may     be any of a number of triggering conditions which trigger the     display of a message to a player encouraging the player to visit a     stationary gaming device. Triggering conditions may include the     following: (a) the stationary gaming device is within a predetermine     distance of the mobile gaming device; (b) the stationary gaming     device has a higher betting limit than the mobile gaming device; (c)     the stationary gaming device supports the same game that the player     has been playing on his mobile gaming device; (d) the stationary     gaming device supports the same game that the player had played in     the past; (e) the stationary gaming device supports a game on which     the player had experienced good results in the past (e.g., a game on     which the player had won more than $100 in the past); (f) the     stationary gaming device features a new game (e.g., a new game that     the casino wishes to test; e.g., a new game that a manufacture     wishes to test; e.g., a new game that the casino wishes to     popularize); and any other triggering conditions.     -   In various embodiments, a mobile gaming device, or any mobile         device, may serve as an information display or information         conduit for nearby objects, people, or other things or entities.         In various embodiments, a player may hold the mobile gaming         device close to a stationary gaming device in order to find out         information about the stationary gaming device. For example, a         player may hold up a mobile gaming device close to a stationary         gaming device in order to find out historical gaming results at         the stationary gaming device. Information that may be revealed         on a mobile gaming device about a stationary gaming device may         include the following: (a) the last outcome; (b) the last         payout; (c) the last 10 outcomes; (d) the last 10 payouts; (e)         the last X outcomes; (f) the last X payouts; (g) the last time a         bonus round was reached; (g) the net winnings of the prior         player at the stationary gaming device; (h) the gross winnings         of the prior player at the stationary gaming device; (i) the         amount won at the stationary gaming device in the last hour; (j)         the amount won at the stationary gaming device in the last X         period of time; (k) the last time a jackpot was won; (l) the         largest payout to be won in the last hour; (m) the identity of         any celebrity that has played at the stationary gaming device;         and any other information about the stationary gaming device.     -   In various embodiments, a mobile gaming device may reveal         information about a gaming table. The mobile gaming device may         reveal results or outcomes at the table. For example, the mobile         gaming device may display representations of cards that are         currently in play at the table. For example, the mobile gaming         device may display representations of the community cards that         are currently in play in a game of Texas Hold'em. In various         embodiments, a mobile gaming device may display representations         of current pot sizes or beta amounts at a table. The mobile         gaming device may display representations of hidden or secret         cards. For example, a mobile gaming device may show         representations of cards that a player holds in his hand, or         representations of cards yet to be deal. In various embodiments,         a mobile gaming device may show: (a) the identify of one or more         players at a table; (b) a gaming history of one or more players         at a table (e.g., the most recent outcome achieved by a player         at the table; e.g., the winnings for the player at the table in         the last hour); (c) the identify of the dealer at the table; (d)         the stakes at the table; (e) the betting limit at the table; (f)         the last X cards dealt at the table; (g) the manufacturer of the         table; (h) the availability of a seat at the table (e.g., the         mobile gaming device may show that there is one seat available         at the table; e.g., the mobile gaming device may show that there         are 3 people in line to sit at the table); (i) information about         a dealer at the table; (j) information about how much players         have won when playing with this dealer; and any other         information about the game at the table, the outcomes at the         table, the players at the table; and any other information about         the table.     -   In various embodiments, a mobile gaming device may display         information about a restaurant. The mobile gaming device may         display information including: (a) an indication of one or more         menu items that are in the restaurant; (b) an indication of         prices in the restaurant; (c) in indication of ratings or         reviews for the restaurant; (c) an indication of the available         seating in the restaurant; (d) information about a chef at a the         restaurant; (e) an indication of an expected wait time; (f) an         indication of an expected time to be served dinner; (g) an         indication of any special items being served; (h) an indication         of any promotion associated with the restaurant (e.g., a current         promotion may offer drinks at half price); and any other         information about the restaurant.     -   In various embodiments, a mobile gaming device may display         information about a store or other retail establishment. A         mobile gaming device may display information including: (a)         product listings; (b) product prices; (c) promotions (e.g., a         promotion may offer 50% on all items in the store); (d) product         reviews; (e) product sizes (e.g., sizes for clothes); (f) number         available of every product, and any other information about the         store.     -   In various embodiments, a mobile gaming device may have         different settings in terms of what types of information or how         much information it may reveal about a stationary gaming device,         about a person, or about any other entity. In various         embodiments, different settings may allow a player to view         information about different time periods. A first setting may         allow a player to view information from a particular time in the         past. A second setting may allow a player to view information         from another, more distant time in the past. For example, a         first setting may allow a player to view historical game         information about a stationary gaming device up to 10 minutes in         the past. In other words, the player may be able to see what         outcomes have occurred at the gaming device in the past ten         minutes. However, outcomes which had occurred at the gaming         device more than ten minutes ago may not be available for         viewing by the player. A second setting of a mobile gaming         device may allow a player to view historical gaming results from         a stationary gaming device up to one our in the past. In various         embodiments, a setting may determine the range over which a         mobile gaming device may display information about a stationary         gaming device or other person, object, or entity. At a first         setting, the mobile gaming device may be able to display         information about a stationary gaming device that is up to 10         feet away. At a second setting, the mobile gaming device may be         able to display information about a stationary gaming device         that is up to 50 feet away. If a player has a mobile gaming         device at the second setting, the player may be able to sweep         the mobile gaming device in an arc with his hand and to thereby         find out information about many different stationary gaming         devices without having to move his feet. In various embodiments,         settings may determine the type of stationary gaming device,         person, object, or other entity about which a mobile gaming         device may display information. For example, in a first setting,         a mobile gaming device may display information only about         stationary gaming devices that feature video poker. In a second         setting a mobile gaming device may display information only         about stationary gaming devices that feature slot machine games.     -   In various embodiments, prior to displaying information about a         stationary gaming device, person, or other object or entity, a         mobile gaming device must first detect the stationary gaming         device. Further, in various embodiments, it must be decided         which stationary gaming device among several proximate gaming         devices will be the one for which information will be displayed         on the mobile gaming device. For example, the mobile gaming         device may be proximate to several stationary gaming devices. It         must then be determined which of the several proximate         stationary devices will be the one for which information is         displayed on the mobile gaming device. In various embodiments, a         mobile gaming device will display information about the         stationary gaming device to which it is closest. In various         embodiments, a mobile gaming device will display information         about the stationary device to which it is most nearly being         pointed. For example, a mobile gaming device may have side or         face which may be assumed to constitute the front of the mobile         gaming device. When the front of the mobile gaming device is         facing or pointing towards a particular stationary gaming         device, then the mobile gaming device may display information         about the stationary gaming device. In various embodiments, a         mobile gaming device may display information about a stationary         gaming device which is facing in the direction of the mobile         gaming device. Thus, for example, the mobile gaming device may         display information about a first stationary gaming device that         is further away than is a second stationary gaming device if the         first stationary gaming devices faces in the direction of the         mobile gaming device and the second stationary gaming device         faces in a different direction.     -   In various embodiments, a player may pay to have particular         settings on his mobile gaming device, where such settings         determine the amount of information that may be displayed on the         mobile gaming device. For example, a player may pay 5 per day         for a first setting in which he can hold his mobile gaming         device up to a stationary gaming device and see the last 10         outcomes of the stationary gaming device displayed on his mobile         gaming device. The player may pay 10 per day for a second         setting in which he can hold his mobile gaming device up to a         stationary gaming device and see the last 100 outcomes of the         stationary gaming device displayed on his mobile gaming device.         In various embodiments, a mobile gaming device may receive         information such that it is capable of displaying the         information available for any possible setting. However, the         mobile gaming device may withhold information or not display         certain information that it has received based on its current         setting. For example, a mobile gaming device may be in a first         setting where it may only display the last 10 outcomes that have         occurred on a stationary gaming device. The stationary gaming         device may, in fact, communicate to the mobile gaming device the         last 100 outcomes that have occurred at the stationary gaming         device. However, the mobile gaming device may only display 10 of         those outcomes because of its current setting. Were the mobile         gaming device in a second setting, the mobile gaming device         might display all 100 of those outcomes. In various embodiments,         a mobile gaming device may request from a stationary gaming         device, from the casino server, or from any other source only         the information that it may communicate to a player based on the         current setting of the mobile gaming device. -   29. Tailored Ads in Virtual Game Environments Various virtual game     environments, interactive environments, role-playing environments,     virtual worlds, virtual communities and other environments currently     exist or may exist in the future. Examples include Second Life,     EverQuest, World of Warcraft, and Guild Wars. Such environments may     include slots, mediums, or other opportunities to display     promotions, such as advertisements. The promotions may pertain to     the virtual world or to the real world. For example, the promotions     may be advertisements for products in the real world. For example, a     virtual world billboard may advertise a soft drink that is actually     sold and drunk in the real world.     -   In various embodiments, players or patrons of a virtual         environment may register or otherwise supply information about         themselves. For example, a player may provide a name and email         address when registering to play in a virtual gaming         environment. Other information about the player may be derived         in other ways. For example, information about the player may be         collected from his playing habits. For example, information         about the player may be collected detailing times of day when         the player is active in the virtual community. From such         information, for example, the player's sleeping hours and eating         hours may be deduced. In various embodiments, information about         a player may be derived from interacting with his computer. For         example, the interaction of the player's computer with the         server operating the virtual environment may provide information         about the player's physical location.     -   In various embodiments, information about a player or         participant in a virtual environment may be used in selecting         which promotions will be presented to the player. In various         embodiments, information about a player or participant in a         virtual environment may be used in conjunction with current         circumstances, such as time of day, in presenting promotions to         the player.     -   In various embodiments, a particular location in a virtual world         may display different promotions depending on which players are         currently viewing that location. For example, suppose a player         is driving on a road in a virtual world.     -   The road may include a billboard which displays advertisements         to passing cars. The player's real address may be on record with         the server operating the virtual world. The real address may be         in West Virginia, for example. Accordingly, the virtual world         may present a promotion on the billboard that relates to a         business in West Virginia. For example, the promotion may be an         advertisement for a take-out restaurant near to the player's         house in West Virginia. When a second player drives by the same         billboard in the virtual world, a different promotion may be         displayed to the second player. The different promotion may be a         promotion that is tailored to information about the second         player, such as to the second player's home address in the real         world. In various embodiments, two players may see the same         virtual location, but may see different promotions at the same         location. Thus, it may be as if the two players are in parallel         virtual universes in that they are in the same place at the same         time, but see different things. The promotions shown to the         players may be tailored to the players' respective information.     -   In various embodiments, promotions shown to a player may be         chosen (e.g., by the game server) based on the time of day. For         example, if it is local noon for a player in the real world, a         promotion may be shown for a fast food restaurant. If it is the         evening, a promotion may be shown for a prime-time TV show. -   30. Pay a person to receive ads on his cell phone—In various     embodiments, a user of a mobile device, such as of a cell phone or     mobile gaming device, may be paid to receive promotions at his     mobile device. The person may receive payment from his wireless     carrier and/or from marketers. As payment, a person may receive     cash, discounts off a cell phone bill (e.g., the person may have his     cell phone bill reduced from $40 to 35), gift certificates (e.g.,     gift certificates for the products being promoted by a marketer     providing promotions to the person), and any other benefit. A person     may agree to have a certain quantity of promotions downloaded to his     mobile device. The quantity may include some quantity of playing     time. For example, the quantity may include 1 hour's worth of     promotions per month. The quantity may include some total number of     promotions (e.g., 20 promotions per month). The quantity may include     some total bit or byte quantity of promotions. For example, the     quantity may include 30 megabytes worth of promotions downloaded per     month. A person may receive differing payments or benefits depending     on the quantity of promotions downloaded. For example, a person who     has 20 minutes of promotions downloaded per week may receive a 10     benefit per month, while a person who has 10 minutes of promotions     downloaded per week may receive a 4 benefit per month.     -   In various embodiments, promotions downloaded may include ring         tones. One possible benefit of a ring tone is that it may be         heard not only by the owner of mobile device (e.g., a cell         phone), but it may also be heard by others in the vicinity of         the owner when the device rings. Thus, if the ring tone promotes         a particular product or service, the promotion may reach more         than just one person. In various embodiments, a person may be         paid or may receive a benefit for downloading a particular ring         tone. In various embodiments, a person may receive a benefit for         using a particular ring tone. For example, a cellular phone may         report to the wireless carrier (or to any other business or         authority) on the usage of a particular ring tone. A person may         be paid according to this reported usage. In various         embodiments, a person may be paid according to the number of         phone calls he receives and according to the number of times a         particular ring tone is thereby played. In various embodiments,         a person may be paid according to his or her location at the         time that a ring tone is played from his cellular phone. For         example, a person may be paid more if his ring tone goes off in         a crowded or frequently trafficked area than if the ring tone         goes off in an isolated area. In various embodiments, a person         may be paid according to the time of day that a ring tone goes         off. For example, a person may be paid more if a ring tone goes         off during a busy time of day (e.g., during a lunch hour) than         during a time of day when most people are at home or are at work         in a particular area. -   31. Software which prevents or discourages the mobile device from     presenting unauthorized ads (or other things). In various     embodiments, a party that is not affiliated with the casino may     attempt to transmit data for a promotion to a mobile gaming device.     The party may wish to have a promotion presented on the mobile     gaming device. In doing so, however, the party may be circumventing     the casino, and may thereby be avoiding making payments to the     casino that are rightfully owed to the casino.     -   In various embodiments, a mobile gaming device may include         software to prevent the presentation of unauthorized promotions.     -   In various embodiments, data for an authorized promotion may         include a tag, label, or other associated data. The tag may be         an authorization code, for example. A mobile gaming device may         include software which can determine whether a tag is valid or         not. For example, a valid tag may include a digital signature         from the casino server. The mobile gaming device may include         software that can check whether the tag is a valid digital         signature of the casino server. In various embodiments, a         digital signature may incorporate data from a promotion. Thus,         another party may be unable to effectively take a digital         signature from an authorized promotion and move it to an         unauthorized promotion.     -   In various embodiments, data associated with a promotion may         include a time stamp. The time stamp may indicate, for example,         when a promotion was approved by the casino server or by some         other authoritative body. A mobile gaming device may include         software for determining whether a time stamp represents a time         in the recent past. If the time represented by a time stamp is         too far in the past, then the mobile gaming device may prevent         the promotion from being displayed. In various embodiments, a         promotion must be displayed within a certain amount of time of         receiving a time stamp. Thus, a party that attempts to intercept         an old time stamp, attach it to an unauthorized promotion, and         then display the promotion, may be foiled. In some embodiments,         a time stamp provided by an authorized body, such as by the         casino server, may incorporate the data of the promotion. Thus,         another party may be unable to take a time stamp associated with         one promotion and use it for another.     -   In various embodiments, data associated with a promotion may be         encrypted en route to a mobile gaming device. For example, the         casino server may use its private key to encrypt data associated         with a promotion. The mobile gaming device may then use the         casino server's public key to decrypt data associated with the         promotion, and to then present the unencrypted promotion. A         party that attempts to transmit an unauthorized promotion to a         mobile gaming device may not have access to the casino server's         private key. Therefore, the party may not be able to pass off         the unauthorized promotion as a legitimate promotion.     -   In various embodiments, a human screener may view a presentation         of a promotion before it is presented to a person via a mobile         gaming device. If the promotion does not meet certain criteria,         the human screener may prevent the promotion from being         presented. The human screener may flag the promotion, for         instance, with a tag that prevents the casino server from         transmitting the promotion to a mobile gaming device. -   32. Player Reactions In various embodiments, a player may have the     opportunity to indicate a reaction to a promotion. The player may     indicate, for example, that he liked the promotion, that the     promotion was funny, that the promotion was relevant to him, that     the promotion was of the right length, that the promotion was of the     right volume, that the promotion was for a product or service about     which the player would like to learn more, and so on. The player may     rate the promotion using a numerical rating, for example. For     instance, the player may give the promotion a rating of 1 to 5 on a     scale of relevance. In various embodiments, a player may furnish a     negative reaction as well. A player may indicate that a promotion     was offensive, irrelevant, too long, too distracting, or in any     other way undesirable.     -   A player's reaction to a promotion may be forwarded by the         casino server to the marketer that originated the promotion. The         marketer may thereby have an opportunity to design a better         promotion. The player's reaction may also be used to build a         profile for the player. The profile may include a set of         preferences of the player. The profile may be used to determine         future promotions that should be presented to the player.     -   A player's reaction to a promotion may be used in preventing a         promotion from being presented to other players. A player may         flag a promotion as offensive or inappropriate, for example. The         casino server may then decide not to present the promotion any         further. In some embodiments, if a player flags a promotion, a         casino representative may view the promotion. The casino         representative may then decide whether or not to continue         presenting the promotion. In various embodiments, a promotion         may no longer be presented if it is flagged by a predetermined         number of players. For example, if three or more players tag a         promotion as inappropriate, the casino server may cease         presentation of the promotion. The casino server may halt the         presentation of a promotion by failing to transmit data for the         promotion to any further mobile gaming devices. The casino         server may halt the presentation of a promotion by sending a         signal to one or more mobile gaming devices with data describing         the promotion already stored locally on the mobile gaming         devices. The casino server may instruct the mobile gaming         devices not to present such promotions. The casino server may         instruct the mobile gaming devices to delete such promotions. -   33. Prevent presentation of promotions that are confusing and look     like symbols; compliance of promotion with standards In various     embodiments, certain types of promotions may be barred from     presentation because of the possibility that the promotions would be     confusing or misleading. As an illustration, a promotion may be     presented in place of a symbol. If the promotion looks like a     jackpot symbol, then a player may believe he has won a large prize     when the promotion lines up with several real jackpot symbols. The     player would be sorely disappointed to find that he had not won as     much as he thought.     -   In various embodiments, the casino server may contain software         for analyzing images associated with promotions. The software         may use image recognition or image comparison algorithms to         ensure that images shown in promotions look sufficiently         distinct from images typically seen in a game. For example,         image processing algorithms may be used to determine a border         for a symbol. Image processing algorithms may similarly be used         to determine a border for a graphic in a promotion. The two         borders may be represented with looped black lines, for example.         The two borders may then be overlain on top of one another. If         the two borders fall within a predetermined distance of one         another (e.g., within three pixels) over their entire lengths,         then the borders may be construed to define similar shapes. The         promotion may be barred based on the fact that it contains a         graphic which is shaped similarly to a symbol. In various         embodiments, coincidence of both shape and color may be         sufficient reason to bar a promotional graphic. As will be         appreciated, many other algorithms may be used to perform image         recognition and/or image comparison.     -   In various embodiments, comparisons of promotional images with         images used in a game may be performed on a mobile gaming         device. For example, a mobile gaming device may store software         for performing image comparisons and/or image recognition. In         various embodiments, comparisons of promotional images with         images used in a game may be performed on a stationary gaming         device.     -   In various embodiments, promotions may be restricted such that         the promotions may be presented only with certain games. The         restrictions may be based on a comparison between images in a         promotion and between images in a game. If images in a promotion         look too similar to the images in a game, presentation of the         promotion may be unallowable in conjunction with a game.         However, if images in a promotion do not look too similar to         images in a game, then the presentation of the promotion may be         allowed in conjunction with a game. Thus, in various         embodiments, it may be permissible to present a given promotion         in conjunction with a first game, but not in conjunction with a         second game. For example, suppose a promotion comprises an image         that is presented on the reels of a slot machine game. The         promotion may be presented with a first slot machine game, but         not with a second slot machine game.     -   In various embodiments, it may be permissible to present a         promotion at a certain location on a display screen, but not at         another location. It may be impermissible to present a promotion         in a first location on a display screen if images in the         promotion might be confused with standard game elements or         images. For example, if an image in a promotion looks like a         symbol used in a game, it may be impermissible to present the         promotion within the game area (e.g., on the reel symbols; e.g.,         in an area where cards are typically dealt). However, it may         still be permissible to present the promotion in another area of         the screen. For example, it may still be permissible to present         the promotion to the right of the game area. As another example,         a promotion may include images which show numerals (e.g., “5%         APR on a new credit card!”). It may be impermissible to present         such a promotion in a location where numerals are typically         presented as part of a game. For example, a presenting a         promotion with images of numerals may be impermissible near an         area where a player's credit balance is typically displayed.         Thus, in various embodiments, software may compare images in         promotions to images typically seen at different areas of a         display screen. Image comparison algorithms may be used. If the         images of a promotion are too similar to those of standard game         elements in a particular area of a display screen, then it may         be made impermissible for the promotion to be presented in that         area. On the other hand, if there is not too much similarity         between the images in the promotion and between the images of         typical game elements in an area, then the promotion may be         presented in that area. In various embodiments, humans may         visually compare images, or may otherwise make a determination         as to whether it is permissible for a promotion to be displayed         in a particular area of a display screen. The foregoing may be         understood with respect to a mobile gaming device or to a gaming         device, in various embodiments.     -   In various embodiments, it may be permissible to present a         promotion at one time during a game, but not at another time.         For example, certain images associated with a game may typically         arise only during a single stage of the game. Such images may         not arise at other points in the game. Accordingly, the         presentation of promotions showing similarly looking images may         be permissible only during those stages when the game images are         not typically displayed. For example, a slot machine game may         include a bonus round. The bonus round may include images that         are not seen in the earlier stages of the game. Thus,         presentation of promotions which include images similar to those         shown in the bonus round may be impermissible during the bonus         round, but permissible during other stages of the game.     -   In various embodiments, certain colors may be impermissible in a         promotion. Such colors may be the same colors as symbols or         other game elements. In various embodiments, certain shapes may         be impermissible in a promotion. Such shapes may be shapes used         as symbols or other game elements. In various embodiments, a         list, table, or other indicator of prohibited shapes may be         published, posted, transmitted to marketers, or otherwise made         available.     -   In various embodiments, game developers may submit graphics or         indications of graphics used in their games. The game developers         may submit such graphics to a regulator, to a marketer, to a         casino server, or to another party. Graphics from different         games may be stored together or may be stored in association         with one another, such as being stored in a single database or         set of linked databases. Marketers may then refer to the         graphics in order to design promotions that have dissimilar         graphics. A regulator or casino server may similarly compare         game graphics to promotional graphics to ensure there is not a         conflict.     -   In various embodiments, a consulting company or other company         may have access to a database or other conglomeration of         graphics used in games. The company may help marketers design         promotions that do not use graphics too similar to those used in         games. In various embodiments, the consulting company may have         private access to the conglomeration of symbols, e.g., so game         developers do not have to share knowledge of graphics with         competing developers.     -   In various embodiments, humans may be used to compare graphics         used in promotions to graphics used in a game. In various         embodiments, a human tester may play a game that features         promotions. The human may later be asked whether they were ever         confused or mislead by a promotion. For example, the human may         ask whether they ever thought they had won something when they         did not. If the human reports that they were not confused, then         the promotions may be permitted as part of the game. In various         embodiments, a test may require a certain number of people to         report that they were not confused. For example, a test must         involve at least six people, and all must report that they were         not confused by a promotion.     -   In various embodiments, sounds associated with a promotion may         be compared to the sounds featured in a game. In various         embodiments, an algorithm may be used to compare the sounds of a         promotion with the sounds featured in a game. The algorithm may         compare tones, tempos, rhythms, musical keys, volume,         instrumental sounds (e.g., violin, e.g., piano), or any other         feature of sounds. In various embodiments, if the sounds of a         promotion are deemed to be too similar to sounds featured in a         game, presentation of the promotion may made impermissible in         the game. In various embodiments, if sounds in a promotion are         deemed to be too similar to those in a game, the promotion may         be presented, but without the sounds. For example, the promotion         may be presented using only graphics.     -   In various embodiments, humans may listen to sounds from a         promotion and from a game. The human may use his own judgment to         determine whether the sounds of the promotion might be confused         with the sounds of the game. In various embodiments, a group of         test subjects listens to both sounds. Only if none, or less than         a predetermined number of the test subjects says that the sounds         would not be confusing may the promotion be allowed for         presentation in the game. In various embodiments, one or more         test subjects is allowed to play a game in which a promotion was         presented. The test subjects are then asked whether they were         confused by the promotion, e.g., whether they at any time         thought that sounds from the promotion had something to do with         the game. Only if the subjects report no confusion may the         promotion be used in the game, in various embodiments.     -   In various embodiments, it may be impermissible to show faces in         promotions. In various embodiments, it may be impermissible to         show a face in a promotion without having received prior         approval from the face's owner. In various embodiments, software         or a human may analyze graphics associated with a promotion to         determine whether there are any faces in the promotion. For         example, face recognition algorithms may be used to detect faces         in promotions. In various embodiments, the use of certain         celebrity faces may be impermissible in promotions. For example,         the celebrities may have failed to supply permission for         appearing in promotions. Humans or algorithms, such as face         recognition algorithms, may be used to compare faces appearing         in promotions to known faces of celebrities so as to ensure that         the celebrities do not appear in the promotions.     -   In various embodiments, humans or software may be used to ensure         a promotion does not contain certain words. For example,         software may check for vulgar or obscene words.     -   In various embodiments, software may ensure that data for a         promotion is in a satisfactory format. For example, software may         check that data for an image meets certain dimensions or pixel         constraints. For example, the software may verify that image         data represents an image of exactly 100 pixels by 200 pixels. As         another example, software may verify that an image contains the         proper color encoding. For example, software may verify that an         image for a promotion uses eight bits to describe each of the         three primary colors. In various embodiments, software may         verify that data describing a promotion is not excessive. For         example, a promotion may be limited to 10 megabytes or to any         other limit. -   34. Location limited ads In various embodiments the casino server     may transmit instructions to a mobile gaming device. The     instructions may tell the mobile gaming device to present a     promotion when, or only when the mobile gaming device is in a     particular area of a casino. For example, the casino server may     instruct the mobile gaming device to present a promotion only when     the mobile gaming device is within ten feet of a particular     restaurant. As another example, the casino server may instruct the     mobile gaming device to present a promotion only when the mobile     gaming device is in the swimming area of a casino. -   35. Offering to transfer a player from a mobile gaming device to a     stationary gaming device In various embodiments, a player may be     involved in gaming on a mobile gaming device. The player may wish to     play the same game at a stationary gaming device. For example, the     stationary gaming device may afford the player a place to sit, may     feature a larger display screen, may feature improved sound, or may     have any other advantage or convenience. In various embodiments, the     casino server may offer the player the chance to transfer from     playing a game at a mobile gaming device to playing a game at a     stationary gaming device. The player may have the chance to transfer     to a stationary gaming device and pay the same game that he had been     playing at a mobile gaming device. -   36. Product or Store placement on mobile device In some embodiments,     as a player moves near a product or a store, a image or video     associated with the product or store may be placed on the mobile     device. In some embodiments, the store and/or manufacturer may pay     for such placement each time it happens. In some embodiments, the     image or video may be part of a game, such as a symbol on a slot     machine. If the symbol comes up on the slot machine or other game, a     coupon for the product or store may be provided to the player. The     store or manufacturer may provide and/or pay for the coupon in some     implementations. The casino may pay for the coupon in other     implementations. In some embodiments, a mobile gaming device may     sense an RFIP tag on a product in a store and use the information     identifying the product to determine what promotion to show. -   37. Preferences are triggered when you walk near a store that     carries the preferred items. In some embodiments, a player may     identify a set of preferences and or a set of player preferences may     be obtained (e.g., for a remote system such as Amazon.com,     Google.com, etc.). In one implementation, for example, an Amazon.com     wish list may be obtained by the mobile device. When the mobile     device is near an item from the wish list, a store related to an     item from the wish list, an item related to an item from the wish     list, etc. a promotion may be triggered on the mobile gaming device. -   38. Derive Information from Game Play. In some embodiments,     information about a player may be derived from game play on a mobile     gaming device. For example, some demographic groups may exhibit     common game play patterns (e.g., high income players wager more,     older players play more slot games, etc.). An observed pattern of     game play may be used to place a player in an estimated demographic     group, which may be used to direct promotion to the player. -   39. Sharing information with Advertisers. In some embodiments,     information obtained about a player (e.g., demographic information     entered by a player, identification information, preference data     obtained by observing behavior, and so on) may be shared and or sold     to advertisers. -   40. Tracking activity not on a mobile device. Some modern casino     chips have RFID or other trackable components. Some modern casino     tables have the ability to track such chips as they are played. In     some embodiments, a mobile gaming device may communicate with such a     table to track the play of a player at a casino table. Accordingly,     mobile gaming devices may track which tables a player is playing at     and how the player is performing at the tables. Such information may     be used to direct promotions to the player as described herein. -   41. Images of player. In some embodiments, an image of the player my     be captured with one or more cameras in a casino environment.     Location information from a mobile gaming device may be used to     identify the location of a player so that the cameras may target the     player. The image information may be used to direct advertising at     the player. For example, the image may be used to determine a     players mood, age, etc. In some embodiments, a image may be verified     through a reference image of the player, such as an image from a     drivers license or other ID used to check into a hotel room, etc. -   42. ADS FROM THE INTERNET ARE DIVERTED TO A MOBILE GAMING DEVICE In     various embodiments, marketers, advertisers, or other parties     wishing to place advertisements may determine a particular group or     type of people who would make a desirable audience for an     advertisement. For example, a marketer of luxury cars may wish to     target advertisements to high income individuals, while a marketer     of chewing gum may wish to target advertisements to teenagers. An     advertiser on the Internet may choose to place banner ads or other     ads that will be shown in conjunction with published content, such     as with news articles, web logs (blogs), encyclopedia entries,     pictures, or other content. An advertiser on the Internet may choose     to place banner ads or other ads that will be shown in conjunction     with search results, such as in conjunction with the results of a     Google or Yahoo search.     -   In some embodiments, an advertiser, marketer, or other party may         decide to show ads on the Internet. The advertiser may designate         a target audience for one or more of the ads. The advertiser may         explicitly or implicitly designate the target audience. If the         designation is explicit, the advertiser may specify an age,         income level, home region, or any other demographic information         or any other information about a desired target audience. If the         designation is implicit, the advertiser may specify a particular         place, time, piece of content, or other circumstance under which         an ad will be shown. The circumstances specified by the marketer         may favor a particular target audience. For example, if the ad         is to be placed in an online game of combat, then the ad may be         most likely to be seen by males aged 15 to 35. Therefore, such         an audience may be implicitly targeted.     -   In various embodiments, a target demographic may be determined         for an advertiser, marketer, or other party who intends to place         ads on the Internet. For example, the advertiser may have         specified the target audience, or the advertiser may have         specified where his ads are to be placed, thereby allowing an         inference as to the advertiser's target audience. In various         embodiments, one or more players of mobile gaming devices may be         found at a casino such that the players are part of the target         demographic. The players may be found based on information         obtained about the players, such as based on information         provided by the players when registering at a casino hotel or         when signing up for a player tracking card. Once players have         been found who fall within a target demographic for an         advertiser, the ads of the advertiser may be shown to such         players. The ads may be shown to the players while the players         engage in play at a mobile gaming device. For example, ads may         be shown on the reels of slot machines in games played by the         players. In various embodiments, ads that were intended to be         shown in the Internet may instead by shown to players using         mobile gaming devices. The players may be of a demographic being         targeted by the ads.     -   The advertiser may originally submit ads to an advertising         network on the Internet. The advertising network may include a         business, Web site, exchange, or other entity that receives         advertisements and places (or “serves”) the advertisements with         appropriate publishers or content providers. Thus, the         advertising network may be a middleman between purchasers of         advertising space (e.g., advertisers) and sellers of advertising         space (e.g., content publishers). When ad advertiser submits ads         to an advertising network with a particular target audience         specified (e.g., with a particular demographic specified), the         ads may be diverted from the Internet to being used on gaming         devices, such as on mobile gaming devices. The ads may otherwise         receive similar treatment to what they would have received had         they been shown on the Internet. For example, if an advertiser         has purchased 1000 impressions on the Internet for his         advertisement, the advertisement may instead be shown 1000 times         to players of mobile gaming devices. If an advertiser has         purchased a large or prominent display area for his ad on the         Internet, the ad may instead be shown in a large or prominent         portion of a display screen of a mobile gaming device. In         various embodiments, an advertiser may be asked whether he         agrees to have his ads shown on a mobile gaming device. The         advertiser may agree or may decline and indicate that he wishes         for his ads to be shown only on the Internet.     -   In various embodiments, ad advertiser may visit an advertising         network or other place where he can buy advertising space. The         advertisers may find on the advertising network that one         category of available advertising space includes advertising         space on mobile gaming device. The advertiser may then have the         opportunity to purchase such space. -   43. Follow a person with Ads In some embodiments, promotions     targeted at a single person may follow a persons movements through a     casino. For example, as a person moves along a path, devices along     the path may display promotions directed at the person. The     promotions may include personalized information, such as a name of     the person, his friends, his address, any information obtained about     his preferences or events he has been involved in, and so on. The     promotions may include audio directed at the person, such as a     reference to the person by name, a jingle, and so on. -   44. Embodiments herein are combinable It should be recognized that     while some embodiments are described as separate embodiments, that     some or all embodiments and concepts described herein may be     combined in any way.

A method comprising: receiving, by at least one processor, data associated with a promotion displayable on a mobile gaming device; identifying, by the at least one processor, a similarity metric between an image in the data associated with the promotion and an image associated with a game executable in the mobile gaming device, in which identifying the similarity metric comprises: comparing, by the at least one processor, a border of a first graphic within the image in the data associated with the promotion with a second graphic within the image associated with the game, and measuring, by the at least one processor, a distance between the border of the first graphic and the border of the second graphic; displaying, by the at least one processor, the game in a first area of a screen of the mobile device; identifying, by the at least one processor, a second area of the screen, different from the first area; displaying the promotion in the second area, in response to determining that the similarity metric meets a threshold; and displaying, by the at least one processor, the promotion in the first area of the screen, in response to determining that the similarity metric does not meet the threshold.
 2. The method of claim 1, further comprising formatting, by the at least one processor, the data associated with the promotion such that the promotion is displayable on the screen.
 3. The method of claim 1, in which identifying the similarity metric further comprises comparing, by the at least one processor, colors in the image associated with the promotion with those of the image associated with the game.
 4. The method of claim 1, in which identifying the similarity metric further comprises comparing, by the at least one processor, shapes in the image associated with the promotion with those of the image associated with the game.
 5. The method of claim 1, further comprising identifying, by the at least one processor, a sound similarity between sounds provided by the promotion with those of the game.
 6. An apparatus comprising: at least one processor; and a memory, in which the memory stores instructions which, when executed by the processor, direct the at least one processor to: receive data associated with a promotion displayable on a mobile gaming device; identify a similarity metric between an image in the data associated with the promotion and an image associated with a game executable in the mobile gaming device, in which, to identify the similarity metric, the instructions, when executed, direct the at least one processor to: compare a border of a first graphic within the image in the data associated with the promotion with a second graphic within the image associated with the game, and measure a distance between the border of the first graphic and the border of the second graphic; display the game in a first area of a screen of the mobile device; identify a second area of the screen, different from the first area; displaying the promotion in the second area, in response to determining that the similarity metric meets a threshold; and display the promotion in the first area of the screen, in response to determining that the similarity metric does not meet the threshold.
 7. The apparatus of claim 6, in which the processor is further configured to format the data associated with the promotion such that the promotion is displayable on the screen.
 8. The apparatus of claim 6 in which the processor is further configured to compare colors in the image associated with the promotion with those of the image associated with the game.
 9. The apparatus of claim 6, in which the processor is further configured to compare shapes in the image associated with the promotion with those of the image associated with the game.
 10. The apparatus of claim 6, in which the processor is further configured to identify a sound similarity between sounds provided by the promotion with those of the game.
